During this period the moon reaches its last quarter phase on Tuesday February
14th. At that time the moon will be located ninety degrees west of the sun and
will rise near 0100 local standard time (LST) for observers located in the
mid-northern latitudes. This weekend the waning gibbous moon will severely
hamper meteor observations as the moon will be above the horizon most of the
night. Only a few hours after dusk will be free of interfering moonlight.
Unfortunately meteor rates are lowest at this time but you might get lucky and
see a fireball as now through April are good times to try and see early evening
fireball activity. The estimated total hourly rates for evening observers this
week is near two for observers in the northern hemisphere and five for those
south of the equator. For morning observers the estimated total hourly rates
should be near five as seen from mid-northern latitudes and eight from
mid-southern latitudes. The actual rates will also depend on factors such as
personal light and motion perception, local weather conditions, alertness and
experience in watching meteor activity. Morning rates are reduced this week due
to moonlight.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning February
11/12. These positions do not change greatly day to day so the listed
coordinates may be used during this entire period. Most star atlases (available
at science stores and planetariums) will provide maps with grid lines of the
celestial coordinates so that you may find out exactly where these positions are
located in the sky. A planisphere or computer planetarium program is also useful
in showing the sky at any time of night on any date of the year. Activity from
each radiant is best seen when it is positioned highest in the sky, either due
north or south along the meridian, depending on your latitude. It must be
remembered that meteor activity is rarely seen at the radiant position. Rather
they shoot outwards from the radiant so it is best to center your field of view
so that the radiant lies at the edge and not the center. Viewing there will
allow you to easily trace the path of each meteor back to the radiant (if it is
a shower member) or in another direction if it is a sporadic. Meteor activity is
not seen from radiants that are located below the horizon. The positions below
are listed in a west to east manner in order of right ascension (celestial
longitude). The positions listed first are located further west therefore are
accessible earlier in the night while those listed further down the list rise
later in the night.

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 10:24 (156) +08. This
position lies in southwestern Leo, five degrees southwest of the bright first
magnitude star Regulus (Alpha Leonis). Due to the large size of this radiant,
Antihelion activity may also appear from Cancer, Sextans, Crater, and western
Virgo as well as Leo. This radiant is best placed near 0100 LST, when it lies on
the meridian and is located highest in the sky. Rates at this time should be
near one per hour no matter your location. With an entry velocity of 30 km/sec.,
the average Antihelion meteor would be of slow velocity.

Studies of video radiants by Sirko Molau and Juergen Rendtel has revealed a
radiant active in Hercules this time of year. The Beta Herculids (BHE) are only
active for five nights and reach maximum activity on Monday February 13th.
Hourly rates on that morning should be near one shower member per hour as seen
from the northern hemisphere. Those situated south of the equator should average
slightly less than one meteor per hour. The first signs of activity from this
radiant appear on the morning of February 10th. The radiant position on the 13th
lies at 16:24 (246) +24. This position lies in western Hercules, three degrees
north of the third magnitude star Beta Herculis. The radiant is best placed
during the last dark hour before dawn, when it lies highest above the horizon in
a dark sky. At 56km/sec. the Beta Herculids would produce mostly swift meteors.

The Alpha Centaurids (ACE) are active from a radiant located at 14:20 (215) -60.
This position lies in southeastern Centaurus directly between the two brilliant
stars Hadar (Beta Centauri) and Rigel Kentaurus (Alpha Centauri). The radiant is
best placed during the last dark hour before dawn, when it lies highest above
the horizon in a dark sky. At this position, these meteors are only visible
south of 30 degrees north latitude. The further one is located south (down to
60S) the better the radiant is situated in the sky. Current rates from the
southern hemisphere is near one per hour. At 56km/sec. the Alpha Centaurids
would produce mostly swift meteors.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately three sporadic meteors per hour during the last hour before dawn
as seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near six per
hour as seen from rural observing sites and four per hour during the evening
hours. Locations between these two extremes would see activity between the
listed figures. Morning rates are reduced this week due to moonlight.

The table below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Antihelion (ANT) - 10:24 (156) +08   Velocity 30km/sec
Northern Hemisphere - 1 per hr Southern Hemisphere - 1 per hour

Alpha Centaurids (ACE) 14:20 (215) -60   Velocity 56km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - 1 per hour

Beta Herculids (BHE) 16:24 (246) +24   Velocity 56km/sec
Northern Hemisphere - 1 per hr Southern Hemisphere - <1 per hour

Clear Skies!

Hello all,

Just joined the group but have been a member of IMO for a few years.

From what I've read I understand MetRec is the official standard because of the
uncompressed data and this in turn allows particular processing.

I personally know of several individuals and from Geert I've found out about
some other groups that are using UFO Capture. I was wondering just how many
people in the IMO are currently using UFO capture (and indeed any other motion
detect software such as HandyAvi.)

Is there any structure for the observations to be collected and reported in the
manner of the regular reports we see for MetRec?

I'd be interested to hear from anyone who is using UFO Capture.

All the best,

Bill.

Dear All,

I invite you to read the brief article about one of the SOHO comets (SOHO-1954)
written by Rainer Kracht.
On the begin of February, Gareth Williams (from MPC) published a new orbit on
MPEC 2012-B23.

I found that the comet C/2008 Y12 moves in a very similar orbit as a stream of
southern delta Aquarids. Rainer Kracht confirmed that the comet may be a member
of the Machholz Interplanetary Complex.

The 2012 International Meteor Conference (IMC) will take place on La Palma,
Canary Islands, Spain, from September 20th (Thursday evening) to 23rd
(Sunday lunchtime). More details can be found on the website
http://www.imo.net/imc2012/ .
Flights are still very low priced so we advice to book early this year to
avoid the more expensive fares that will be charged by air lines if you
wait until the summer months to book. The IMC registration form is
available on the 2012 IMC website.

The geographic location of the Canary Islands might be of particular
interest for participants from the other side of the Atlantic to attend
this first IMC in a Spanish speaking country while the exceptional natural
beauty of the island deserves to consider an extra holiday. Extra days and
tourism packages can be ordered at very attractive prices. Discover the
numerous offers on the 2012 IMC website!

Looking forward to see you all at La Palma,

Paul Roggemans

Hello Bill

I'm using UFO capture, you can see some info about my setup here:
http://deepspaceplace.com/meteor.php

The software is really quite robust and powerful, and Mr. Sonota is
always helpful if you have a question or problem.

Currently I'm not reporting the results, but I hope to in the future.
I believe it can be done using UFOAnalyzer. I suggest to contact
'Stephane' in the UFO capture forums:

During this period the moon reaches its new phase on Tuesday February 21st. At
that time the moon will be located near the sun and will not be visible at
night. This will be the best time this month to view meteor activity. This
weekend the waning crescent moon will rise during the late morning hours and
will not interfere with meteor observations. The estimated total hourly rates
for evening observers this week is near three for observers in the northern
hemisphere and five for those south of the equator. For morning observers the
estimated total hourly rates should be near seven as seen from mid-northern
latitudes and fourteen from mid-southern latitudes. The actual rates will also
depend on factors such as personal light and motion perception, local weather
conditions, alertness and experience in watching meteor activity.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning February
18/19. These positions do not change greatly day to day so the listed
coordinates may be used during this entire period. Most star atlases (available

celestial coordinates so that you may find out exactly where these positions are
located in the sky. A planisphere or computer planetarium program is also useful
in showing the sky at any time of night on any date of the year. Activity from

are listed in a west to east manner in order of right ascension (celestial

accessible earlier in the night while those listed further down the list rise
later in the night.

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 11:00 (165) +05. This
position in southwestern Leo is very easy to find as the brilliant planet Mars
currently lies only seven degrees to the northeast. Due to the large size of
this radiant, Antihelion activity may also appear from Crater, Sextans,
southwestern Coma Berenicids, and western Virgo as well as Leo. This radiant is
best placed near 0100 local standard time (LST), when it lies on the meridian
and is located highest in the sky. Rates at this time should be near one per
hour no matter your location. With an entry velocity of 30 km/sec., the average
Antihelion meteor would be of slow velocity.

The last of the Alpha Centaurids (ACE) may be seen this weekend from a radiant
located at 14:53 (223) -62. This position lies in southeastern Centaurus, two
degrees southeast of the brilliant zero magnitude star Rigel Kentaurus (Alpha
Centauri). The radiant is best placed during the last dark hour before dawn,
when it lies highest above the horizon in a dark sky. At this position, these
meteors are only visible south of 25 degrees north latitude. The further one is
located south (down to 60S) the better the radiant is situated in the sky.
Current rates from the southern hemisphere would be less than one per hour. At
56km/sec. the Alpha Centaurids would produce mostly swift meteors.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately six sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near
fourteen per hour as seen from rural observing sites and four per hour during
the evening hours. Locations between these two extremes would see activity
between the listed figures.

The table below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Antihelion (ANT) - 11:00 (165) +05   Velocity 30km/sec
Northern Hemisphere - 1 per hr Southern Hemisphere - 1 per hour

Alpha Centaurids (ACE) 14:53 (223) -62   Velocity 56km/sec

As seen from the northern hemisphere, March is the slowest month for meteor
activity. No major annual showers are active and only two very weak minor
showers produce activity this month. The sporadic rates are also near their
annual minimum so there is not much to look forward to this month except for the
evening fireballs that seem to peak this time of year from the northern
hemisphere. This could be due to the fact the Antiapex radiant lies highest
above the horizon this time of year during the evening hours. From the southern
hemisphere, activity from the Centaurid complex begins to wane with only the
weak activity visible from Norma and perhaps others areas nearby. At least
southern sporadic rates are still strong to make the late summer viewing a bit
more pleasurable.

During this period the moon reaches its first quarter phase on Thursday March
1st. At that time the moon will be located ninety degrees east of the sun and
will set near 0100 local standard time (LST) from mid-northern latitudes. This
weekend the waxing crescent moon will set during the late evening hours and will
not interfere with meteor observations during the more active morning hours. The
estimated total hourly rates for evening observers this week is near three for
observers in the northern hemisphere and five for those south of the equator.
For morning observers the estimated total hourly rates should be near six as
seen from mid-northern latitudes and fifteen from mid-southern latitudes. The
actual rates will also depend on factors such as personal light and motion
perception, local weather conditions, alertness and experience in watching
meteor activity.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning February
25/26. These positions do not change greatly day to day so the listed
coordinates may be used during this entire period. Most star atlases (available

they shoot outwards from the radiant so it is best to center your field of view
so that the radiant lies at the edge and not the center. Viewing there will
allow you to easily trace the path of each meteor back to the radiant (if it is

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 11:20 (170) +03. This
position in southeastern Leo is very easy to find as the brilliant planet Mars
currently lies only five degrees to the north. Due to the large size of this

your location. With an entry velocity of 30 km/sec., the average Antihelion
meteor would be of slow velocity.

The Gamma Normids (GNO) is a weak shower best seen from the southern hemisphere.
This shower is only visible south of forty degrees north latitude. The further
one is located south (down to 50S) the better the radiant is situated in the
sky. Expected rates from the southern hemisphere is currently less than one per
hour, even with the radiant located high in the sky. The current radiant
position lies at 15:36 (234) -53. This position lies in western Norma, five
degrees east of the third magnitude star Zeta Lupi. The radiant is best placed
during the last dark hour before dawn, when it lies highest above the horizon in
a dark sky. At 56km/sec. the Gamma Normids would produce mostly swift meteors.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately five sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near
fourteen per hour as seen from rural observing sites and four per hour during
the evening hours. Locations between these two extremes would see activity
between the listed figures.

The list below presents a condensed version of the expected activity this week.

Hi Bill,

sorry for the late reply - I was busy with the monthly report recently
and work through my email backlog now.

It's not quite right that MetRec is the official standard of IMO - it's
the standard of the IMO Video Meteor Network. Of course, there are
plenty of IMO and non-IMO members world-wide who use UFOCapture -
several times more than there are MetRec users. But the software you are
using is only secondary - more important is what you want to do with
your observations.

I had plenty of discussions with SonotaCo when we met at the MODWG
workshop in Noordwijk back in April 2010. From that I learned, how the
SonotaCo network is organized, and what their strengths and weaknesses
are. Most (all?) Japanese UFOCapture observers are organized in the
SonotaCo network. Two years ago it was of the order of 100 cameras
contributing to that network. They are "self-organized" - i.e. there is
some website where the observers can upload their data, and everyone can
access the data set for his own analysis. The raw data are kept with the
observers because of their tremendous size. SonotaCo has been compiling
analyses on annual data sets, and the quality check is done purely by
the software. That scales quite well, but if someone creates poor data
he would not know unless he is analysing the data himself.

In the IMO network we follow a different approach: All the data is
uploaded and collected at a central site, and they are all manually
quality-checked. That's a tremendous amount of work, but the observers
get direct feedback when they are doing mistakes, or what might be
improved. Also, we create reports on a monthly basis (which is
time-consuming as well) to give our observers a direct feedback about
the use of their data.

Both approaches are limited by resources. The SonotaCo network would not
be able to include all the UFOCapture observers from other parts in the
world, so they concentrate on the Japanese observations only. Adding
further observations would also make little sense, as they are focussing
on double-station work which requires dense camera networks. Individual
cameras from somewhere else in the world would not be helpful.
In the IMO network we are focussing on single-station work, which is why
in principle we can include data from everywhere. Our approach is not
scaling well, though. When have been growing significantly over the
years, optimized our processes and involved more people to keep track
with the growing number of cameras, but if their number would double all
of the sudden, we would not manage to keep the level of feedback and
quality. And this is the only reason why we are restricting ourself to
MetRec - because a mixture of MetRec, UFOCapture and other data would
make the quality check, data collection and analysis much more
time-consuming and we could not handle it anymore.

This is the current situation to the best of my knowledge, and this is
why you have plenty of single observers or small local network in the
world, who use UFOCapture or self-written software, but either have to
take the extra effort to collect and analyse their own data (which is
the exception) or just collect video meteors without doing something
about them in the end (which is the rule).

And this is why in my opinion the selection of software is secondary.
You should rather think of what you want to achieve with your
observations and what you want to do with your data (don't expect that
someone will contact you and ask about your data), which options you
have (e.g. joining some local/global initiative or do everything on your
own), and what that means for your camera setup incl. the choice of
software.

Best wishes,
Sirko

PS: The situation may improve with the unified database VMO that will
allow the central collection of observations independent of the
software, but I don't dare to give another estimate when the VMO will
have achieved that state.

Hi all,

In France for exemple, we have a database named boam , http://boam.fr/?lang=en 
, and at this moment , Stéphane (one the database administrator) is able to
convert Ufocapture data in the futur VMO XML format as defined in WGN 38.1 . For
the moment , we are waiting for a feedback of this.

Best Wishes

Hi Bill,

sorry for the late reply - I was busy with the monthly report recently
and work through my email backlog now.

It's not quite right that MetRec is the official standard of IMO - it's
the standard of the IMO Video Meteor Network. Of course, there are
plenty of IMO and non-IMO members world-wide who use UFOCapture -
several times more than there are MetRec users. But the software you are
using is only secondary - more important is what you want to do with
your observations.

I had plenty of discussions with SonotaCo when we met at the MODWG
workshop in Noordwijk back in April 2010. From that I learned, how the
SonotaCo network is organized, and what their strengths and weaknesses
are. Most (all?) Japanese UFOCapture observers are organized in the
SonotaCo network. Two years ago it was of the order of 100 cameras
contributing to that network. They are "self-organized" - i.e. there is
some website where the observers can upload their data, and everyone can
access the data set for his own analysis. The raw data are kept with the
observers because of their tremendous size. SonotaCo has been compiling
analyses on annual data sets, and the quality check is done purely by
the software. That scales quite well, but if someone creates poor data
he would not know unless he is analysing the data himself.

In the IMO network we follow a different approach: All the data is
uploaded and collected at a central site, and they are all manually
quality-checked. That's a tremendous amount of work, but the observers
get direct feedback when they are doing mistakes, or what might be
improved. Also, we create reports on a monthly basis (which is
time-consuming as well) to give our observers a direct feedback about
the use of their data.

Both approaches are limited by resources. The SonotaCo network would not
be able to include all the UFOCapture observers from other parts in the
world, so they concentrate on the Japanese observations only. Adding
further observations would also make little sense, as they are focussing
on double-station work which requires dense camera networks. Individual

In the IMO network we are focussing on single-station work, which is why
in principle we can include data from everywhere. Our approach is not

Subject: Meteor Activity Outlook for March 3-9, 2012
lunroimousa
Send Email Send Email
 
During this period the moon reaches its full phase on Thursday March 8th. At
that time the moon will be located opposite the sun in the sky and will be above
the horizon the entire night. This weekend the waxing gibbous moon will set
during the early morning hours, allowing a few hours of meteor viewing under
dark conditions. The estimated total hourly rates for evening observers this
week is near two for observers in the northern hemisphere and three for those
south of the equator. For morning observers the estimated total hourly rates
should be near six as seen from mid-northern latitudes and fifteen from
mid-southern latitudes. The actual rates will also depend on factors such as
personal light and motion perception, local weather conditions, alertness and
experience in watching meteor activity. Evening rates this week are reduced due
to bright moonlight.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning March 3/4.
These positions do not change greatly day to day so the listed coordinates may
be used during this entire period. Most star atlases (available at science
stores and planetariums) will provide maps with grid lines of the celestial
coordinates so that you may find out exactly where these positions are located
in the sky. A planisphere or computer planetarium program is also useful in
showing the sky at any time of night on any date of the year. Activity from each
radiant is best seen when it is positioned highest in the sky, either due north
or south along the meridian, depending on your latitude. It must be remembered
that meteor activity is rarely seen at the radiant position. Rather they shoot
outwards from the radiant so it is best to center your field of view so that the
radiant lies at the edge and not the center. Viewing there will allow you to
easily trace the path of each meteor back to the radiant (if it is a shower
member) or in another direction if it is a sporadic. Meteor activity is not seen
from radiants that are located below the horizon. The positions below are listed
in a west to east manner in order of right ascension (celestial longitude). The
positions listed first are located further west therefore are accessible earlier
in the night while those listed further down the list rise later in the night.

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 11:44 (176) +00. This
position lies in western Virgo, only two degrees southwest of the fourth
magnitude star Zavijava (Beta Virginis). Due to the large size of this radiant,
Antihelion activity may also appear from the nearby constellations of Crater,
Sextans, Corvus, southwestern Coma Berenicids, and eastern Leo as well as Virgo.
This radiant is best placed near 0100 local standard time (LST), when it lies on
the meridian and is located highest in the sky. Rates at this time should be
near one per hour no matter your location. With an entry velocity of 30 km/sec.,
the average Antihelion meteor would be of slow velocity.

The Gamma Normids (GNO) is a weak shower best seen from the southern hemisphere.
This shower is only visible south of forty degrees north latitude. The further
one is located south (down to 50S) the better the radiant is situated in the
sky. Expected rates from the southern hemisphere is currently less than one per
hour, even with the radiant located high in the sky. The current radiant
position lies at 16:00 (240) -52. This position lies in central Norma, three
degrees southwest of the fourth magnitude star Gamma Normae. The radiant is best
placed during the last dark hour before dawn, when it lies highest above the
horizon in a dark sky. At 56km/sec. the Gamma Normids would produce mostly swift
meteors.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately five sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near one per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near
fourteen per hour as seen from rural observing sites and two per hour during the
evening hours. Locations between these two extremes would see activity between
the listed figures. Evening rates are reduce this week doe to the bright
moonlight.

The list below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Antihelion (ANT) - 11:44 (176) +00   Velocity 30km/sec
Northern Hemisphere - 1 per hr Southern Hemisphere - 1 per hour

Gamma Normids (GNO) 16:00 (240) -52   Velocity 56km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - <1 per hour

Clear Skies!

Dear Colleagues:

I've taken the unusual step of posting here because this very persistent, but
apparently natural, fireball has attracted a great deal of interest in the UK
and across the globe, judging by the mass of e-mails I've received since the
event occurred.

At present, the complete tally of sightings looks likely to be around 300, as
I've received or been notified of more than that so far. However, as you may
imagine, I am still attempting to identify duplicates!

In addition, the object's longevity (probably 30-45 seconds or more) meant a
significant number of people managed to image part of the flight, especially the
latter stages, which has helped create further publicity.

I have already posted details from my preliminary analysis of the first 43 more
complete reports that arrived within 24 hours of the event happening, at:

http://www.popastro.com/phpBB2/viewtopic.php?t=16810

on the SPA's Observing Forum. My intention is to update that topic as more data
becomes available, and I would ask if you or any of your contacts require
information about the event, but have no observations to send, that you refer
people to that topic rather than writing to me! Everyone who wrote/writes to me
will get a reply eventually, but for those who did not see the event, that could
be some weeks away.

The end of the trail, over southern England, was much better observed than the
start, which looks to have been around 1000 km further north, probably somewhere
between the Orkney, Shetland and Faeroe Islands.

What I would ask is that if anyone has received sightings probably of this
meteor from the Faeroes or even Iceland, or ships at sea in the area north of
Scotland, I would welcome having as full a report as possible on what was seen
and when.

Many thanks in advance for any assistance!

Folks,

after another intensive consistency check, the full 2011 data set of the
IMO Video Meteor Network is now available online at
http://www.imonet.org/database.html
At this time, the database contains 1,063,057 meteors, collected by 59
observers in 4277 observing nights and 231,878 hours of effective
observing time.

Happy analysing. :)

During this period the moon reaches its last quarter phase on Thursday March
15th. At that time the moon will be located ninety degrees west of the sun and
will rise near 0200 local daylight time (LDT) for observers located in the
mid-northern latitudes. This weekend the waning gibbous moon will severely
hamper meteor observations as the moon will be above the horizon most of the
night. Only an hour or two after dusk will be free of interfering moonlight.
Unfortunately meteor rates are lowest at this time but you might get lucky and
see a fireball as now through April are good times to try and see early evening
fireball activity. The estimated total hourly rates for evening observers this
week is near one for observers in the northern hemisphere and two for those
south of the equator. For morning observers the estimated total hourly rates
should be near three as seen from mid-northern latitudes and six from
mid-southern latitudes. The actual rates will also depend on factors such as
personal light and motion perception, local weather conditions, alertness and

Many IMC 2011 participants had important
cultural expectations from the local organizer of this event because they knew
the astrocultural valences of the Romanian Society for Meteors and Astronomy
(SARM), and the place of the 30th IMC was even an European Capital
of Culture, the city of Sibiu in Transylvania, Romania.
And obviously, with limits and merits, SARM
enthusiastically did its best to honor these expectations and this jubilee IMC,

During this period the moon reaches its new phase on Thursday March 22th. At
that time the moon will be located near the sun and will not be visible at
night. This weekend the waning crescent moon will rise during the early morning
hours but will not interfere with meteor observations. The estimated total
hourly rates for evening observers this week is near three for observers in the
northern hemisphere and four for those south of the equator. For morning
observers the estimated total hourly rates should be near seven as seen from
mid-northern latitudes and thirteen from mid-southern latitudes. The actual
rates will also depend on factors such as personal light and motion perception,
local weather conditions, alertness and experience in watching meteor activity.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning March 17/18.
These positions do not change greatly day to day so the listed coordinates may

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 12:40 (190) -05. This
position lies in western Virgo, only three degrees south of the famous third
magnitude double star Porrima (Gamma Virginis). Due to the large size of this
radiant, Antihelion activity may also appear from the nearby constellations of
Crater, Corvus, and eastern Leo as well as Virgo. This radiant is best placed
near 0200 local daylight time (LDT), when it lies on the meridian and is located
highest in the sky. Rates at this time should be near two per hour no matter

even with the radiant located high in the sky. The current radiant position lies
at 16:56 (254) -51. This position lies in central Norma, three degrees southwest
of the fourth magnitude star Gamma Normae. The radiant is best placed during the
last dark hour before dawn, when it lies highest above the horizon in a dark
sky. At 56km/sec. the Gamma Normids would produce mostly swift meteors.

On Thursday morning, March 22, activity from the Zeta Serpentids (ZSE) may begin
to be noticed. This shower is active on only five mornings with peak activity
occurring on the 24th. Rates would likely be less than one shower member per
hour, even at maximum activity. The radiant is located near 17:05 (256) -04. The
area of the sky is located in a blank portion of central Ophiuchus, some eight
degrees northeast of third magnitude Zeta Ophiuchi. The radiant is best placed
during the last dark hour before dawn, when it lies highest above the horizon in
a dark sky. At 64km/sec. the Zeta Serpentids would produce mostly swift meteors.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately five sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near ten per
hour as seen from rural observing sites and three per hour during the evening
hours. Locations between these two extremes would see activity between the
listed figures.

During this period the moon reaches its first quarter phase on Friday March
30th. At that time the moon will be located ninety degrees east of the sun and
will set near 0100 local daylight time as seen from the mid-northern latitudes.
This weekend the waxing crescent moon will only be visible during the early
evening hours and will not interfere with meteor observations. The estimated
total hourly rates for evening observers this week is near three for observers
in the northern hemisphere and four for those south of the equator. For morning
observers the estimated total hourly rates should be near seven as seen from
mid-northern latitudes and twelve from mid-southern latitudes. The actual rates
will also depend on factors such as personal light and motion perception, local
weather conditions, alertness and experience in watching meteor activity.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning March 24/25.
These positions do not change greatly day to day so the listed coordinates may
be used during this entire period. Most star atlases (available at science
stores and planetariums) will provide maps with grid lines of the celestial
coordinates so that you may find out exactly where these positions are located
in the sky. A planisphere or computer planetarium program is also useful in
showing the sky at any time of night on any date of the year. Activity from each
radiant is best seen when it is positioned highest in the sky, either due north
or south along the meridian, depending on your latitude. It must be remembered
that meteor activity is rarely seen at the radiant position. Rather they shoot
outwards from the radiant so it is best to center your field of view so that the
radiant lies at the edge and not the center. Viewing there will allow you to
easily trace the path of each meteor back to the radiant (if it is a shower
member) or in another direction if it is a sporadic. Meteor activity is not seen
from radiants that are located below the horizon. The positions below are listed
in a west to east manner in order of right ascension (celestial longitude). The
positions listed first are located further west therefore are accessible earlier
in the night while those listed further down the list rise later in the night.

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 13:08 (197) -07. This
position lies in southern Virgo, five degrees northwest of the first magnitude
star Spica (Alpha Virginis). Due to the large size of this radiant, Antihelion
activity may also appear from the nearby constellations of Crater, Corvus,
extreme eastern Hydra and northern Centaurus as well as Virgo. This radiant is
best placed near 0200 local daylight time (LDT), when it lies on the meridian
and is located highest in the sky. Rates at this time should be near two per
hour no matter your location. With an entry velocity of 30 km/sec., the average
Antihelion meteor would be of slow velocity.

This weekend is prime time to try and view any activity from the Zeta Serpentids
(ZSE).  This shower is active on only five mornings with peak activity occurring
on the 24th. Rates would likely be less than one shower member per hour, even at
maximum activity. The radiant is located near 7:12 (258) -05. The area of the
sky is located in a blank portion of central Ophiuchus, some eight degrees
northeast of third magnitude Zeta Ophiuchi. The radiant is best placed during
the last dark hour before dawn, when it lies highest above the horizon in a dark
sky. At 64km/sec. the Zeta Serpentids would produce mostly swift meteors.

Later in this period, activity from the Zeta Cygnids (ZCY) will begin. This
activity is visible from March 27 through April 13 with maximum occurring on
April 5. On the 27th the  radiant position lies at 19:42 (295) +38. This
position lies in western Cygnus, lying directly between the third magnitude
stars Delta Cygni and Albireo (Beta Cygni). The radiant is best placed during
the last dark hour before dawn, when it lies highest above the horizon in a dark
sky. Due to the northern declination of the radiant, this activity is not well
seen from the southern hemisphere. No matter your location, rates at this time
are expected to be less than one per hour. At 44km/sec. the Zeta Cygnids would
produce meteors of average velocity.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately five sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near ten per
hour as seen from rural observing sites and three per hour during the evening
hours. Locations between these two extremes would see activity between the
listed figures.

The list below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Antihelion (ANT) - 13:08 (197) -07   Velocity 30km/sec
Northern Hemisphere - 2 per hr Southern Hemisphere - 2 per hour

Zeta Serpentids (ZSE) 17:12 (258) -05  Velocity 64km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - <1 per hour

Zeta Cygnids (ZCY)   19:42 (295) +38   Velocity 44km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - <1 per hour

Meteor activity picks up a bit during April as two major showers are active
during the month. The first of these, the Lyrids, are active from the 16th
through the 25th, with a pronounced maximum on the 22nd. The Eta Aquariids start
appearing near the 28th and reach maximum activity during the first week in May.
Sporadic rates are low but steady as seen from the mid-northern hemisphere (45
N). Sporadic rates seen from the mid-southern hemisphere (45 S) rise this month
toward a maximum in July.

During this period the moon reaches its full phase on Friday April 6th. At that
time the moon will be located opposite the sun and will be in the sky all night
long. This weekend the waxing gibbous moon will set during the early morning
hours, allowing a few hours of dark skies for observing before the start of
morning twilight. This window of opportunity shrinks with each passing night
until late in the week when the moon is near full and in the sky all night long.
The estimated total hourly rates for evening observers this week is near two for
observers in the northern hemisphere and three for those south of the equator.
For morning observers the estimated total hourly rates should be near seven as
seen from mid-northern latitudes and twelve from mid-southern latitudes. The
actual rates will also depend on factors such as personal light and motion
perception, local weather conditions, alertness and experience in watching
meteor activity. Even rates are reduced during this period due to moonlight.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning March
31/April 1. These positions do not change greatly day to day so the listed
coordinates may be used during this entire period. Most star atlases (available

they shoot outwards from the radiant so it is best to center your field of view

are listed in a west to east manner in order of right ascension (celestial
longitude). The positions listed first are located further west therefore are
accessible earlier in the night while those listed further down the list rise
later in the night.

The following showers are expected to be active this week:

The large Antihelion (ANT) radiant is currently located at 13:08 (204) -09. This
position lies in central Virgo, four degrees northwest of the first magnitude
star Spica (Alpha Virginis). Due to the large size of this radiant, Antihelion
activity may also appear from the nearby constellations of Corvus, extreme
eastern Hydra, southwestern Bootes, and northern Centaurus as well as Virgo.
This radiant is best placed near 0200 local daylight time (LDT), when it lies on
the meridian and is located highest in the sky. Rates at this time should be
near two per hour no matter your location. With an entry velocity of 30 km/sec.,
the average Antihelion meteor would be of slow velocity.

Studies of the IMO video database by Sirko Molau and Juergen Rendtel has
revealed a weak radiant active in the constellation of Cygnus this time of year.
The Zeta Cygnids (ZCY) are active from March 27 through April 13 with maximum
activity occurring on April 6. The current radiant position lies at 19:52 (298)
+39. This position lies in central Cygnus, six degrees west of the second
magnitude star Sadr (Gamma Cygni). The radiant is best placed during the last
dark hour before dawn, when it lies highest above the horizon in a dark sky. Due
to the northern declination of the radiant, this activity is not well seen from
the southern hemisphere. No matter your location, rates at this time are
expected to be less than one per hour. At 44km/sec. the Zeta Cygnids would
produce meteors of average velocity.

As seen from the mid-northern hemisphere (45N) one would expect to see

During this period the moon reaches its last quarter phase on Friday April 13th.
At that time the moon will be located ninety degrees west of the sun and will
rise near 0200 daylight saving time (DST) for observers situated in the
mid-northern latitudes. This weekend the waning gibbous moon will rise during
the early evening hours, effectively ruining the sky for nearly the entire
night. This week is the worst time to try and view meteor activity during the
month. Conditions will improve when the moon reaches its last quarter phase and
continues to wane toward new. The estimated total hourly rates for evening
observers this week is near one for observers in the northern hemisphere and two
for those south of the equator. For morning observers the estimated total hourly
rates should be near three as seen from mid-northern latitudes and six from
mid-southern latitudes. The actual rates will also depend on factors such as
personal light and motion perception, local weather conditions, alertness and
experience in watching meteor activity. Rates are reduced during this period due
to severe moonlight.

All,

EuroPlanet has just announced their 'Matrix of Ground- and Space-based
Facilities'. Here you can register if you're willing to contribute to a
professional observing program. Check it out:

http://europlanet-na1.oeaw.ac.at/matrix/

Detlef.


The full announcement reads:

NA1: Matrix of Ground- and Space-based Facilities

Besides of organizing Workshops in the fields of Planetary and Space Sciences
the main goal of NA1 is to provide an interactive matrix of ground-based and
space-based observatories for identifying and fostering coordinated observations
(so-called NA1-Matrix). The target groups for this online-tool are firstly
professionals who are seeking for support of ground-based facilities to their
space-based observations and secondly amateurs who are willing to support
professional research programs.

From February 12-17, 2012, an NA2 Expert Exchange took place at UCL, London to
improve the current NA1 Matrix. The main task to be accomplished was the
enhancement of the already existing input form for ground-based facilities,
including user-friendly tooltips and a simplified procedure of registration and
submission. User submitted entries will now underlie a review system, to ensure
the consistence of the information provided by users. The new input system also
provides the possibility to edit existing entries by the associated user to
assure an up-to-date Matrix and the sustainability of the whole system.

The user-registration and the input-form are now available online under 
http://europlanet-na1.oeaw.ac.at/matrix/.

During this period the moon wanes from its last quarter phase to nearly new.
This weekend the waning crescent moon will rise during the early morning hours,
disturbing the nearby sky but allowing dark views in the opposite direction. The
moon wanes and rises later which each passing night, providing more favorable
circumstances as time goes on. The estimated total hourly rates for evening
observers this week is near three for observers in the northern hemisphere and
four for those south of the equator. For morning observers the estimated total
hourly rates should be near seven as seen from mid-northern latitudes and eleven
from mid-southern latitudes. The actual rates will also depend on factors such
as personal light and motion perception, local weather conditions, alertness and
experience in watching meteor activity. Morning rates are slightly reduced
during this period due to moonlight.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning April 14/15.
These positions do not change greatly day to day so the listed coordinates may
be used during this entire period. Most star atlases (available at science

in a west to east manner in order of right ascension (celestial longitude). The
positions listed first are located further west therefore are accessible earlier
in the night while those listed further down the list rise later in the night.

The following showers are expected to be active this week:

Activity from the Pi Puppids (PPU) begins this weekend from a radiant located at
07:04 (106) -44. This area of the sky is located central Puppis, five degrees
southwest of the third magnitude star Sigma Puppis. This area of the sky is best
seen as soon as it becomes dark during the early evening hours.  No matter your
location, rates will be low, far less than one per hour this early in the
activity curve. Observers located in the southern hemisphere have a much better
view of this activity as the radiant lies higher in the sky. At 18km/sec. the Pi
Puppids would produce meteors of very slow velocity.

The weak shower known as the Sigma Leonids (SLE) becomes active on the 18th and
peaks on the 20th. The radiant is located at 13:32 (203) +05, which actually
lies in northern Virgo near the faint star Sigma Virginis. One might feel this
shower was named for the wrong "Sigma" star, but the case is more likely that
visual observations, made before the advent of video methods, placed the radiant
incorrectly further westward in Leo. This radiant is best placed near 0300 local
daylight time (LDT), when it lies on the meridian and is located highest in the
sky. Rates at this time would be less than one per hour no matter your location.
With an entry velocity of 20 km/sec., the average Sigma Leonid meteor would be
of very slow velocity.

The large Antihelion (ANT) radiant is currently located at 14:32 (218) -15. This
position lies in eastern Libra, five degrees west of the third magnitude star
Zubenelgenubi (Alpha Librae). Due to the large size of this radiant, Antihelion
activity may also appear from extreme eastern Hydra, eastern Virgo, as well as
Libra. This radiant is best placed near 0200 LDT, when it lies on the meridian
and is located highest in the sky. Rates at this time should be near two per
hour no matter your location. With an entry velocity of 30 km/sec., the average
Antihelion meteor would be of slow velocity.

Activity from the Lyrid (LYR) shower is first detectable on April 16th and the
shower reaches maximum activity 6 nights later. The radiant is currently located
at 17:52 (268) +36. This area of the sky is actually located in eastern
Hercules, close to the faint star known as Theta Herculis. The radiant is best
placed just before the break of dawn when the radiant lies highest in the sky.
While Lyrid meteors can be seen in both hemispheres, the north is favored as the
radiant lies much higher in the sky. Rates this early in the activity curve
would be low, less than one per hour no matter your location. At 48km/sec. the
Lyrids would produce meteors of medium-swift velocity.

Studies of the IMO video database by Sirko Molau and Juergen Rendtel has
revealed a weak radiant active in the constellation of Cygnus this time of year.
The Nu Cygnids (NCY) are active from April 18 through May 7 with maximum
activity occurring on April 19. The current radiant position lies at 20:20 (305)
+39. This position lies in central Cygnus, two degrees southwest of the second
magnitude star Sadr (Gamma Cygni). The radiant is best placed during the last
dark hour before dawn, when it lies highest above the horizon in a dark sky. Due
to the northern declination of the radiant, this activity is not well seen from
the southern hemisphere. No matter your location, rates at this time are
expected to be less than one per hour. At 42km/sec. the Nu Cygnids would produce
meteors of average velocity.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately four sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near eight
per hour as seen from rural observing sites and three per hour during the
evening hours. Locations between these two extremes would see activity between
the listed figures. Morning rates are slightly reduced during this period due to
moonlight.

The list below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Pi Puppids (PPU) - 07:04 (106) -44   Velocity 18km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - <1 per hour

Sigma Leonids (SLE) - 13:32 (203) +05   Velocity 20km/sec

During this period the moon reaches its new phase on Saturday the 21st. At this
time the moon will be near the sun and will not be visible at night. This will
be the best time of the month in which to view meteor activity.  As the week
progresses the waxing crescent moon will enter the evening sky but will not be
bright enough to interfere with observing. In addition the moon will set during
the evening hours allowing the more active morning to be free from any
interfering moonlight.  The estimated total hourly rates for evening observers
this week is near three for observers in the northern hemisphere and four for
those south of the equator. For morning observers the estimated total hourly
rates should be near twenty-three as seen from mid-northern latitudes and
nineteen from mid-southern latitudes. The actual rates will also depend on
factors such as personal light and motion perception, local weather conditions,
alertness and experience in watching meteor activity.

The radiant (the area of the sky where meteors appear to shoot from) positions
and rates listed below are exact for Saturday night/Sunday morning April 21/22.
These positions do not change greatly day to day so the listed coordinates may
be used during this entire period. Most star atlases (available at science
stores and planetariums) will provide maps with grid lines of the celestial
coordinates so that you may find out exactly where these positions are located
in the sky. A planisphere or computer planetarium program is also useful in
showing the sky at any time of night on any date of the year. Activity from each
radiant is best seen when it is positioned highest in the sky, either due north
or south along the meridian, depending on your latitude. It must be remembered
that meteor activity is rarely seen at the radiant position. Rather they shoot
outwards from the radiant so it is best to center your field of view so that the
radiant lies at the edge and not the center. Viewing there will allow you to
easily trace the path of each meteor back to the radiant (if it is a shower
member) or in another direction if it is a sporadic. Meteor activity is not seen
from radiants that are located below the horizon. The positions below are listed
in a west to east manner in order of right ascension (celestial longitude). The
positions listed first are located further west therefore are accessible earlier
in the night while those listed further down the list rise later in the night.

The following showers are expected to be active this week:

Activity from the Pi Puppids (PPU) continues this week from a radiant located at
07:16 (109) -45. This area of the sky is located central Puppis, two degrees
southwest of the third magnitude star Sigma Puppis. This area of the sky is best
seen as soon as it becomes dark during the early evening hours. Maximum activity
is predicted to occur on Sunday evening the 22nd (23rd UT). Despite this, rates
less than one per hour are expected, no matter your location. Observers located
in the southern hemisphere have a much better view of this activity as the
radiant lies higher in the sky. At 18km/sec. the Pi Puppids would produce
meteors of very slow velocity.

The weak shower known as the Sigma Leonids (SLE) is active from a radiant
located at 13:40 (205) +04, which actually lies in northern Virgo, four degrees
northeast of the third magnitude star Zeta Virginis. One might feel this shower
was named for the wrong constellation, but the case is more likely that visual
observations, made before the advent of video methods, placed the radiant
incorrectly further westward in Leo. This radiant is best placed near 0300 local
daylight time (LDT), when it lies on the meridian and is located highest in the
sky. Rates at this time would be less than one per hour no matter your location.
With an entry velocity of 20 km/sec., the average Sigma Leonid meteor would be
of very slow velocity.

There is also another radiant active in Virgo this time of year. Video data from
The IMO shows that the h Virginids (HVR) are active from April 22-25 with
maximum activity occurring on the 22nd. On the evening of the 21st (22nd UT),
the radiant is located at 14:16 (214) -11. This position lies on the Virgo/Libra
border, two degrees southeast of the fourth magnitude star Kappa Virginis. The
radiant is best placed near 0200 LDT, when it lies on the meridian and is
highest above the horizon. At 24km/sec. the h Virginids would produce more slow
meteors. Expected rates would also be less than one per hour no matter the date
or your location.

The large Antihelion (ANT) radiant is currently located at 14:56 (224) -16. This
position lies in western Libra, only one degree southeast of the third magnitude
star Zubenelgenubi (Alpha Librae). Due to the large size of this radiant,
Antihelion activity may also appear from extreme eastern Hydra, eastern Virgo,
northwestern Scorpius, as well as Libra. This radiant is best placed near 0200
LDT, when it lies on the meridian and is located highest in the sky. Rates at
this time should be near two per hour as seen from the northern hemisphere and
three as seen from south of the equator. With an entry velocity of 30 km/sec.,
the average Antihelion meteor would be of slow velocity.

The Lyrid (LYR) shower is expected to reach maximum activity on the night of
April 21/22 with rates up to 15 shower members per hour. The radiant is located
at 18:08 (272) +33. This area of the sky is actually located in extreme eastern
Hercules, eight degrees southwest of the brilliant blue-white star Vega (Alpha
Lyrae). The radiant is best placed just before the break of dawn when the
radiant lies highest in the sky. While Lyrid meteors can be seen in both
hemispheres, the north is favored as the radiant lies much higher in the sky.
Rates will fall rapidly after maximum and little activity will be seen the
remainder of the week. At 48km/sec. the Lyrids would produce meteors of
medium-swift velocity. It should be noted that the Lyrids can occasionally
produce bright meteors of fireball class magnitude.

Studies of the IMO video database by Sirko Molau and Juergen Rendtel has
revealed a weak radiant active in the constellation of Cygnus this time of year.
The Nu Cygnids (NCY) are active from April 18 through May 7 with maximum
activity occurring on April 19. The current radiant position lies at 20:44 (311)
+42. This position lies in central Cygnus, two degrees south of the first
magnitude star Deneb (Alpha Cygni). The radiant is best placed during the last
dark hour before dawn, when it lies highest above the horizon in a dark sky. Due
to the northern declination of the radiant, this activity is not well seen from
the southern hemisphere. No matter your location, rates are expected to be less
than one per hour. At 42km/sec. the Nu Cygnids would produce meteors of average
velocity.

As seen from the mid-northern hemisphere (45N) one would expect to see
approximately five sporadic meteors per hour during the last hour before dawn as
seen from rural observing sites. Evening rates would be near two per hour. As
seen from the mid-southern hemisphere (45S), morning rates would be near ten per
hour as seen from rural observing sites and three per hour during the evening
hours. Locations between these two extremes would see activity between the
listed figures.

The list below presents a condensed version of the expected activity this week.
Rates and positions are exact for Saturday night/Sunday morning.

Pi Puppids (PPU) - 07:16 (109) -45   Velocity 18km/sec
Northern Hemisphere - <1 per hr Southern Hemisphere - <1 per hour

Sigma Leonids (SLE) - 13:40 (205) +04   Velocity 20km/sec
Northern Hemisphere - <1 per hr   Southern Hemisphere - <1 per hour

h Virginids (HVR) - 14:16 (214) -11   Velocity 24km/sec
Northern Hemisphere - <1 per hr   Southern Hemisphere - <1 per hour

Antihelion (ANT) - 14:56 (224) -16   Velocity 30km/sec
Northern Hemisphere - 2 per hr   Southern Hemisphere - 3 per hour

Lyrids (LYR) - 18:08 (272) +33   Velocity 48km/sec
Northern Hemisphere - 15 per hr   Southern Hemisphere - 5 per hour

Nu Cygnids (NCY) - 20:44 (311) +42   Velocity 42km/sec
Northern Hemisphere - <1 per hr   Southern Hemisphere - <1 per hour

Clear Skies!

#2398 From: IMC 2012 <imc2012@...>
Date: Sun Apr 22, 2012 11:34 am
Subject: 2012 IMC: financial support from IMO
imc2012@...
Send Email Send Email
 
For 2012 a few conditions have changed to obtain financial support from
IMO to participate at the IMC. Seen the number of requests on one hand and
the limited resources from IMO on the other hand, we decided to impose some
more requirements to obtain funding and also put 1 May as deadline instead
of 1 June. These new conditions may have escaped from your attention so we
recall the conditions to obtain support from IMO. If you are in need for
some support to enable your IMC participation, please mail us as soon as
possible. Be aware to observe the following requirements which should not
cause any problem to dedicated meteor workers.
  As during previous years, IMO is making limited funds available to support
participation in the *IMC* 2012. To apply for support, please e-mail your
application to IMC Liaison Officer Paul
Roggemans<http://uk.mc298.mail.yahoo.com/mc/compose?to=paul.roggemans@gmail.com&\
subject=IMC%20support%20application>.
In order to be eligible for support, the following conditions must be
satisfied:

    1. The application must be submitted by an IMO member, but may also
    request support for other meteor workers.
    2. The proposal must state that all the candidates for whom support is
    requested are committed to attend the IMC (except for unforeseen
    circumstances) if the requested support is granted in full.
    3. Each person for whom support is requested must fill out an IMC
    Registration Form (preferably electronically) prior to filing the
    application. In the "Comments" box of the application, the person must
    specify that support will be requested as well as the name of the IMO
    Member who will file the application.
    4. For each person for whom support is requested, a brief curriculum
    vitae must be included, focusing on aspects relevant to meteor work.
    5. Each person for whom support is requested is expected to present
    either a talk or a poster at the *IMC*. He or she should indicate and
    detail this on the Registration Form.
    6. The application must contain the full paper of each talk and/or each
    poster intended for presentation, in PDF format.
    7. The application must explain the motivation for participating in this
    *IMC *and the importance of this participation to the person or group of
    persons for whom support is requested.
    8. The application must include a budget for travel costs and
    registration, and the amount of support requested. Other sources of
    external support, or their absence, must be mentioned. The proposal must
    also indicate to what extent IMO support is essential to attend the *IMC*
    .

Failing to address in full detail each and every of the above items in the
application will result in its rejection without further consideration.
The applications should reach Paul Roggemans no later than *Tuesday, 2012
May 1*. The IMO cannot be held responsible for applications which are lost
or arrive late.
The IMO Council will endeavor to communicate its decision within two to
three weeks after this deadline. If the requested support is granted in
full, the registration of all candidates involved becomes final. If the
requested support is not granted, or only partially granted, the candidates
involved should inform Paul Roggemans within two weeks after notification
of the IMO Council's decision if they want to sustain or withdraw their
registration. Most likely, the support will consist of waiving registration
fees, which will be settled directly between the IMO and the Local
Organizers. Any additional support, if granted, will be paid in cash at the
*IMC*. It is not possible to get an advance on such additional support
before the IMC.
Should the application be turned down, the 'early' registration fee (i.e.,
without the surcharge for a late application) will still apply provided the
applicant settles this fee within two weeks after the notification of the
rejection.
  We strongly encourage all serious meteor workers who want to attend the *
IMC* 2012, but who are prevented from doing so by financial considerations,
to apply for support.

Dear Astronomy and Meteor Enthusiasts,




This is my first message to the IMO
list which I signed in few months ago.




As a professional astronomer (after 20
years on 4 continents, now working since 2009 for the ING observatory
in La Palma) and a former (about 30 years) and always in my hearth
amateur astronomer (mostly active in my natal Romania and in SARM), I
am very glad to join you through your next IMC to be hosted on our
beautiful island La Palma next September!




In this project I have besides my wife
Gabriela, who starting one year ago strongly negotiated with many
hotels, excursions, guides, etc, to obtain the budget IMC prices to
be able to propose you the first IMC in Spain, right on our island!
We are glad to stress again that we have our local insular
authorities (“Cabildo”) beside us, which kindly agreed last year
to sponsor this astro-touristic project in La Palma!




In general I am quite busy with my ING
observatory duties and my personal research (in two directions, dwarf galaxies
and near Earth asteroids) and also as a father, but I follow your
news on this list and I hope to be able to contribute also
scientifically to your IMC meeting. Specifically, more recently I
became interested in main belt comets and in this sense I might be
interested in (3200) Phaeton and its relation with Geminids (any
potential collaborator? please write me privately).




In any case, we are ensuring you that
since two years ago when we got the idea of proposing you an IMC in
La Palma, we have been doing our best to prepare this dream to come
true and we are putting lots of efforts in this project, along with
our partners, the Cabildo, ORM and IAC (which will receive you to
visit Roque de Los Muchachos Observatory), and of course IMO and our
LOC colleagues in order to offer to those interested to attend the
next IMC hopefully one of the best meteor conference ever, combined
optionally with few extra vacation tours before, in our sub-tropical
Atlantic destination!




Thus, we are here in La Palma, looking
forward to receiving you and hosting the IMC on “La Isla Bonita”!




Best wishes,


Ovidiu and Gabriela Vaduvescu
IMC2012 LOC La Palma

       The 2012 International Meteor Conference (IMC) will take place on La
Palma,

Canary Islands, Spain, from September 20th (Thursday evening) to 23rd

(Sunday lunchtime). More details can be found on the website

http://www.imo.net/imc2012/ .

Flights are still very low priced so we advice to book early this year to

avoid the more expensive fares that will be charged by air lines if you

wait until the summer months to book. The IMC registration form is

available on the 2012 IMC website.



The geographic location of the Canary Islands might be of particular

interest for participants from the other side of the Atlantic to attend

this first IMC in a Spanish speaking country while the exceptional natural

beauty of the island deserves to consider an extra holiday. Extra days and

tourism packages can be ordered at very attractive prices. Discover the

numerous offers on the 2012 IMC website!



Looking forward to see you all at La Palma,



Paul Roggemans
