Hi All,

    I received an APT image from NOAA-17 just after the eruption
of Mt. St. Helens (Washington state, USA) today.  I have uploaded
it to the group.

    The ash and steam plume can be seen as a very small bright area
at about the 4 o'clock area just below and to the right of the
orange dot (Seattle).

    The image file name is noaa-17-20041001192539GMT-s-za.jpg.

Hi Geoff.
I have downloaded the NOAA-17 data from the Archive and cannot see
anything on HRPT. I have made an image of the area around Mt St
Helens and it shows snow on Mt Rainier, Mt Adams and some on Mt Hood,
south of the Columbia.
Mt St Helens shows as a darkish area to the west of Mt Adams, no
obvious emissions. Would assume this eruption was'nt big enough or
the cloud dispersed by the time the sat went over.
Your image was not in the files area last time I looked.
If anyone wants to view the image I made it's at:
http://www.weathersatellite.info/A1946091-vg-corrected.jpg

It's in vegation mode and is about 250kb

Cheers....Mike

Yes, I did the same, Mike, and saw nothing.  I thought I would wait for a
second opinion, though, in case the OP's date or time was wrong.  There is
a report about the eruption here:

   http://news.bbc.co.uk/1/hi/world/americas/3709226.stm

although it doesn't give a time for the eruption.  There's more
information here:

   http://vulcan.wr.usgs.gov/Volcanoes/MSH/CurrentActivity/

which includes: "The event lasted from 11:57 to 12:21 PDT"

so that's around 19:00 UTC (I think, allowing for daylight saving time).
Better check the NOAA-16 pass as well!

For ash, you might also want to check the Ch4 - Ch5 image.

Cheers,
David

Hi David.
I have not checked any other sat passes but seeing as this was a
small event it's possible it will not be visible but I stand to be
corrected.
Seeing that the NOAA-17 pass was nicely cloud free I have made some
3D images if anyone is interested. They were produced with David's
HRPTReader, Groundmap and 3DEM software, data from the NOAA Archive.

The first image is of the Mt St Helens area looking past Mt Rainier
towards the SSE. St Helens being the dark mountain with the dent in
it.
http://www.weathersatellite.info/sthelen4.jpg
About 100kb in size.

The second image is a large format image of the whole Seattle area
centred on St Helens.
http://www.weathersatellite.info/sthelen6.jpg
About 400kb in size.

The third image is a view looking down the Cascades to the south, Mt
Rainier in the foreground.

About 100kb in size.

1300 image: the white cloud lying NE/SW by the Canaries has an interesting
structure - it looks as if cirrus is fraying off its northern edges, along
the full length. Anyone care to interpret this - is it just the higher
parts of the cloud reaching upper level winds?

Apologies if this is a re-send, our spam filter keeps having a row with yahoo

The sub tropical jet stream runs across the Canaries. I think it generally runs
W -> E across the high pressure area. Lying on the beach you can often see 3
cloud layers moving in different directions. Incidentally the polar jet stream
is not doing us any favours
http://squall.sfsu.edu/crws/jetstream.html

and is that the remains of hurricane Lisa heading for us, just NW of the Azores.

Hi Guy.
Yes thats Lisa.
It will merge with the large low that is up near Iceland and run
across the UK. There is a severe weather warning at:
http://www.metoffice.gov.uk/weather/europe/uk/warnings.html

Looks like plenty of rain and some possibility of damaging winds in
places.

Here is an image from the NOAA Archive when Lisa, still technically a
Hurricane, was at 41N 37W....pass was NOAA-17 at 1401utc yesterday.
Data processed with David's HRPTReader.

Might I  ask why this encoding was done?  Is it considered a 'standard'
code  in some circles (like NASA/NOAA) so thus the reason why it was used
instead of some 'easier to decode' standard?


David,

Viterbi and Reed Solomon coding are widely used in satellite transmissions
these days and I'm sure there are several far more competent members who  can
explain the advantages.

Off course digital satellite TV (DVB) uses these codings and 'chips' are
available off the shelf for the decoders for a few £'s owing to mass production
for the domestic market.

MSG was designed during the early days of digital satellite  TV.
Perhaps if it was being designed today they might use the coding parameters
of current day freely available chips?

Remember, meteorological (and other imaging) satellite are not  designed for
home use, as such, so cheap reception and processing equipment  requirements
does not come into the design equation.

John Tellick.

Thanks for your useful input to this discussion.

As to  why the FEC codes are used, I suggest you read my article on page 8 of
GEO  Quarterly #3. It is very likely that chips to perform the required
functions  will be available as soon as there is a demand for them  ....


Alan,

Your article in GEO 3 was very informative and useful - it taught me a  lot.
Regarding chips being available for the standards used for LRIT  you suggest
'as soon as there is a demand.'
Trouble is this particular 'demand' can be counted in hundreds or  low
thousands compared to the many millions of DVB chip sets produced?
So, who is going to put in the development money and will they get back
their investment on such a selective market?

I've another scenario.
Since the direct read-out we receive from geostationary weather satellites
is merely a relay of (raw) data, processed by EUMETSAT, NOAA etc. ground
stations and uplinked back to the 'imaging' satellite in a specific  format -
EUMETSAT, NOAA and other satellite operators could process  the data into the
DVB
(Viterbi and Reed-Solomon) format on the ground, no  problem for them, and
relay that for reception by end users?

I'm not sure about transponder bandwidths on MSG, GOES et al  direct read-out
downlink's also, the format has already (a long time ago)  been decided and
professional systems been built and shipped to receive this  original
specification.

Regarding the 'demise' of interest by young people in not only our hobby  and
amateur radio I find this very sad.
And, I believe the (apparent) lack of interest by young people in  science.

Judging by your comments you must be a similar age to me where when we were
young science was fascinating and many of the 'advantages' we take for granted
  were yet to happen?

Regards,
John Tellick.

Hi John,

We 'constructors' are still alive and kicking, it's just that there is not
much to construct at present, MSG via DVB cannot be bettered except by HRPT
and that's already sorted.  The fun will start when the METOP series come
along.

Cheers, Guy

  APT,  DIGITAL and GEOSTATIONARY WEEKLY STATUS.
   ==========================================
                       Author :   Douglas S Deans.
                       -------------------------------

            APT  STATUS  REPORT -- 4th October 2004
               ==============================


   Satellite             Frequency (MHz)      Status        Image Quality

   NOAA 12                137.500                 on               good
   NOAA 14                137.620                 off
   NOAA 15                137.500                 off           see Note 3.
   NOAA 17                137.620                 on               good


NB. There are no Russian Meteor or Okean satellites transmitting or able
to transmit APT.

CHANGES SINCE LAST REPORT.
None.

THIS WEEK'S POSSIBLE EVENTS.
None expected.

NOTES.

1.  NOAA 9 was permanently deactivated some years ago and is tumbling
freely.  Unfortunately it has a sporadic carrier on 137.500 (varies quickly
according to orientation) and can cause interference to NOAA 12 and
NOAA 15.

2.  NOAA 16's APT transmission system failed a few months after launch.

3. Due to a NOAA 12/15 VHF (137.500) conflict, NOAA 15 will be switched off
from 19th September, 22.00 UTC until 20th October, 18.00 UTC.


LAUNCHES.

The launch of Sich-1M will be NET November 2004.
This project has been about for at least 5 years so I suggest we don't hold
our breath.   Thanks to Ian Deans for providing this information.

NOAA N launch NET 12th February 2005.
NOAA N' launch.....TBA.

       DIGITAL  STATUS  REPORT -- 4th October 2004
          ==================================

CHANGES SINCE LAST REPORT.
None.

THIS WEEK'S EVENTS.
None expected.

  Satellite        Frequency    Mode          Remarks
                           (MHz)
NOAA 12        1698.0       HRPT       Good signal.
NOAA 14        1707.0       HRPT       No data (see note 5)
NOAA 15        1702.5       HRPT*     Backup channel, weaker signal
NOAA 16        1698.0       HRPT*     Good signal (see note 7)
NOAA 17        1707.0       HRPT*     See note 6.
Feng Yun 1C   1700.4       CHRPT     See note 8.
Feng Yun 1D   1700.4       CHRPT     Good signal.
Seastar            1702.5       SeaWifs    signal OK
                                          encrypted


NOTES.

1.   At the NOAA 17 frequency of 1707 MHz occasional interference may be
expected from NOAA 14 at latitudes above 80 degrees. Erratic behaviour of
the inactive NOAA 9 also has proven to be a source of interference at higher
latitudes. NOAA 9 follows a similar track to 17.  Recent reports suggest
that this erratic behaviour is no longer being seen.  My thanks to F. Valk
for keeping us up to date with this problem.

2.  If you have a good LNA and analogue decoder (Timestep for example)
all satellites with "Good signal" or better can already be received using
a 1.5M helical beam (RIG Journal 64) or a small dish (60 to 80 cm) with
helical feed.

3.  * These satellites have channel 3A/B which allows the composition of
     almost true-colour images of daylight passes using R3G2B1
     colour  scheme. For more info on colouring see RIG Journal 69.

4.  ~  10 Channel imager, use colour scheme R1G9B7 or R1G2B7 for
     daylight passes to get near true colour images.

5.  It is believed that during a test to switch off and then back on the
      NOAA 14 AVHRR scan mirror motor that the motor stalled.
      NOAA have confirmed that there are currently no plans to try and
      restart the stalled motor.  There is no imagery available.

6. Problems have developed with STX-3 (1707 MHZ).  Power has dropped from
     approx. 8W to about 2.4W resulting on a greatly reduced signal strength.

7. On Friday 19th September 2003 NOAA 16 developed AVHRR synch. problems
     similar  to those on NOAA 14 (and previously NOAA 15).
     Since then reports have been mixed.  Some periods of good data, some
     poor.

8. Although all channels are functioning on Feng Yun 1C, the image is
     not synchronised so the scan line is distorted.
     This results in having the edge of the earth, or at least the scan
     line, in the centre of the image.

  NOTES.

1.  If necessary the satellite may operate beyond this date.

2. HRIT & LRIT data will not be disseminated through the satellite but will
be  provided via Hotbird satellite in DVB mode.  See the Eumetcast status
report for more information.

3. Meteosat 5 now operates with only one channel.

4. Meteosat 6 is the standby satellite for Meteosat 7.  Whilst in standby is
being used to provide a 10 minute rapid scan service of Europe on HRI.

5. Insat 3A is a combined data and meteorological satellite.

6. GMS-5 ceased VISSR transmissions on 22nd May 2003.  Wefax is now
     derived from GOES-9 (155° E) GVAR and processed to a 140° aspect
     through GMS-5. For further information see :-

Meteosat 6.
Due to the eclipse season between 18 August 2004 (day 04.231) and 05 October
2004 (day 04.279), Slots 46, 47 and 48 may not be available.

Meteosat 7.
Due to the eclipse season between 29 August 2004 (day 04.242) and 12 October
2004 (day 04.286), Slots 1, 2, 47 and 48 may not be available.
Due to Sun colinearity between 3 October 2004 (day 04.277) and 11 October
2004 (day 04.285), there may be no Channel 1 dissemination between 11:42 and
12:02.
On the 5 October 2004, Meteosat7 processing will be changed. This will
improve the timeliness of the product delivery on EUMETCast. The change will
be made  at 12:00. During the transition there is a risk that  products
could be interrupted.

Meteosat 8.
The eclipse season starts on the 30/08/04 and finishes on the 16/10/04.
The image quality could be affected around the midnight repeat cycles.

FSD Products.
Foreign Satellite Data availability during eclipse:
GOES-E (GOES 12) eclipse from 13/08/04 to 04/10/04: no image at 0600 UTC.
GOES-W (GOES 10) eclipse from 14/08/04 to 29/10/04: no image at 0900 UTC.
GMS (GOES 9) eclipse from 13/08/04 to 24/10/04: no image at 1500 UTC,
1600 UTC files are planned as backup.

EARS.
The EARS service will be interrupted for up to 3 hours on Wednesday 6
October for maintenance activity. Detailed information will be provided
closer to the time.

Folks,

Despite reporting on it a number of times in the last few weeks, I forgot to
change the Transponder list for the Eumetcast Service.
Of course it should read :-

  Service          Status              Hotbird Satellite (13° E)

   EARS             On                Transponder 117: 10853.44 MHz
   RSS                On                Transponder 117: 10853.44 MHz
   Meteosat 8      On                Transponder 117: 10853.44 MHz

The transponder came into full operation on 1st October 2004.
My apologies, and thanks to David Taylor for spotting it.

Douglas.

Ouch! An interesting report - no doubt had this happened in the UK all the
top managers would have been promoted!
Seriously though, another example from a whole series of disasters
(Challenger, Herald of Free Enterprise, Chernobyl, Piper Bravo ... ) where
the ultimate causes were not technical but organisational. You need someone
more like me (sociologist)than people with spanners or computers to sort
out these sorts of problems.  Ho hum ....

Hello Guy,

Well, only if the first satellite uses 137.10 Mhz.
If MetOp 1 uses 137.9125 MHz then all is lost - in the UK - or most  parts?

At least our Dutch and other overseas members will have some clean signals
to play with.

This week's ESA TV Exchanges will be partly on Eutelsat W1, and partly on
"Europe by Satellite". The next transmission is:

Metosat and TV weather  forecasting
ESA TV Exchanges

8 October 09:15-09:30 GMT
Replay I:  8 October 16:00-16:15 GMT,  both on:
EUTELSAT W1 at 10° East Transponder  B4 Middle, channel 2, vertical, F=11.089
MHz (SCPC - DVB/MPEG-2), SR=5.632  MS/sec, FEC=3/4

Replay II: 9 October 13:15 -13:30 GMT,  on:
EUTELSAT HOT BIRD at 13° East (DVB/MPEG-2), horizontal, F=12,476 MHz  (MCPC,
Europe by Satellite), SR=27,500 MS/sec, FEC=3/4

This TV Exchange  visits the UK Met Office in London and some of the British
broadcasters who use  its services. Weather prediction has become more
reliable over the years. Our  understanding of climatic phenomena has also
greatly
improved. Powerful  computers now crunch vast quantities of data allowing a
variety of short to  medium term forecasts.

Weather bulletins have become one of the most  watched TV programmes around
the world. The data provided by weather centres  like the Met Office is often
'dressed up' for television.

Earlier this  year, the first of a second generation of Meteosat satellites
renamed Meteosat-8  once in orbit, started routine operations under the
auspices of Eumetsat,  Europe's organisation for the exploitation of
meteorological
satellites.

These improved satellites will allow long-term weather forecasts (beyond
five days) and better short term forecasts of extreme weather situations.
Today's transmission features how better satellite data also lead to better TV
weather forecasts.

The script will be on-line on 8 October as a PDF  document under
http://television.esa.int/photos/MTTV2004.pdf

More  backgroud information can be found on:
http://www.esa.int/SPECIALS/MSG/index.ht

It has been announced that Lockheed Martin will give up all profits that had
been earned from a contract to build the NOAA N Prime satellite damaged in
September 2003 and will repair the spacecraft on a cost-only basis. The
craft was damaged when it fell 1m to the floor due to missing bolts on its
cart.

Douglas.

Those who take Monitoring Times (and the numbers must now be rather limited),
may be interested to hear that they have dropped my weather satellite column
after the December edition.  It has run for some years but the editor tells me
that there is just no interest in monitoring satellites.  Ironically, I have
received more requests for wxsat information during the last few months than
previously.

The last edition includes yet another good image from Chuck Vaughn, together
with a short piece about LRIT.

Personally, I am very sad to lose the column, and also to lose the (small)
income....

My thanks to all who have supported it in the past.

Sorry to hear that, Lawrence.

I used to take MT just to read your column which I did enjoy, but I did
feel their heart wasn't in it somehow, so I dropped MT a year or two back.
Perhaps Kevin can give you more pages in SWM (with an increase in fee!)?
<G>  Or perhaps RadCom or Scientific American?  Your words deserve a wide
airing.

It does seem that the European scene is much more active, and I think we
can thank EUMETSAT and the RF enthusiasts for that.  The presence of
high-quality magazines packed with super articles has kept the armchair
enthusiasts interested as well.  I suspect that if there was cheap LRIT
receiver some US interest would be re-kindled, as would the presence over
there of a EUMETCast-like system.  It will come in time, I am sure.

Cheers,
David

Hi Adrian,

You couldn't quickly explain how you select/setup the Hotbird
channel using DBV viewer under Skyview?

Many Thanks

    Heh, I did the same thing.....and saw the same results...  ;-(

    I've now realised that what I thought was a plume has shown up
on other images before and since.  I guess that I was a little too
"gung ho" in reporting the event.  ;-(  Oh, well......

    N17 went over within a half hour (don't remember the exact times)
of the end of the event, IIRC.

    Yeah, I noticed that as well.  I guess I have to RTFM. :-)))))
