by what time we can hear these burst phases from our set up?

which is the next pridicted date for these events to occur(solar and jupiter
burst)and at what time it will happen?

how to pridict these dates astronomically?

Greetings!

Goodevening sir,  i have downloaded the software radio skypipe II, when i press
the start chart button it starts printing the chart without any antenna
connection to it and anything else, how is this happening without any
connection?

Is it due to inbuilted sound card in laptop?

Is there any way to stop our software from printing charts till we connect
antenna to it?

Can you send me some end results from which i can predict that software is
working properly with the antenna?
                                                   OR
The variations that comes just after connecting the antenna to the laptop which
shows the antenna is properly connected and software is showing the variation
due to radio signals?

Hi Jim, Dave
yes Jim's quite right, it is possible to put two time series onto the one time axis with excel - if Dave wants to know the detail on how to do this he is welcome to email me.

But I suspect that Dave is interested in having having two traces from different observatories running in the same skypipe window concurrently. At real time. I am unaware as to whether this is possible, but it seems to me that the display mechanics in skypipe are clearly there already - for not only two channels but a number of channels can be displayed in real time together. What the coding difficulties are in effectively running RSP in client mode and stand-alone mode (eg) - at the same time - I am unsure. But if anybody could bring such a worthwhile project to fruition it would surely be Jim Sky - he is not only The skypipe guru - he is the creator as well.

Steve
excel is dreadfully complicated,
I do not recommend it to anybody

I may still try to do this though. It is probably the most often requested feature we do not have (besides streaming audio).

SARA members and Jove observers,

DARPA is a serious military research institute that is exploring how to collect information from public networks. They offer a nice prize to the first person/group who reports locations of 10 red, tethered weather balloons that they put up this morning.

From www.science.Slashdot.org:

"As you might have heard, DARPA has announced a network challenge in the vein of the DARPA Grand Challenge. In this challenge, participants are tasked with finding 10 red weather balloons distributed throughout the continental US for 8 hours on December 5. The idea is to get this to be a crowd-sourcing kind of activity, where people will use social media tools to solve this problem..."

If you'd like to cooperate in finding the balloons and get a share of the $40,000 reward, you can join the search here. You can add your name and get your own link to share with friends, or you can share this link. If we win anything, it will buy pizza and beer for folks at the SARA Western Conference -- anything left goes to the treasury. If you have any links to amateur radio operator nets, you might want to email them our address.

Basically how to operate radio sky pipe software step by step with our set up and before set up what shoul be the settings?

Please revert back to me with the steps of operating the software so that i can proceed further as soon as possible.

thank you sir

Does there exist a utility to merge two or more charts such that they show
up as different channels within the same SPD file?

Assuming observer's clocks are accurate to better than a second, and
assuming both charts were generated with the same sampling rate, they should
be easy to merge.  Well, not impossible.

This would be useful when comparing charts from different observers.  The
post-processing equation functionality could then be used to compare the two
original datasets.

Anyway, I was thinking about writing such a utility, but I figured I may as
well ask beforehand as I cannot be the first person to have thought of this.

Dear Mr. Sharma,

I am doing very well, thank you.

I copy Mr Sachin Bhamba <sachin@...> of the S.P.A.C.E organization, and the Radio Jove Technical email list.

We need the assistance of all Radio Jove Participants.

I congratulate you for your enthusiasm in studying and promoting Radio Astronomy.

Re: my semester examinations are starting and i m not at all prepared.i m engaged in promoting radio astronomy.

You must give priority to preparation for your examinations, study well Mathematics and Physics. You will need them to pursue a career in any area of Science and Technology, including Astronomy and Radio Astronomy. Achieve high grades in your examinations.

Re: suggest us ideas for promoting RADIO ASTRONOMY and Radio jove

Members of� S.P.A.C.E can start by reading the very good pages at the Radio Jove site:
http://radiojove.gsfc.nasa.gov/

Ask questions and participate in discussions in the RJ Technical list, you will learn a lot. I do !

Google the words "radio astronomy", I find over 6 million hits.
There is a lot to read !!
Learning about Astronomy has kept me busy for more than half a century.

Visit schools and talk about Science, Technology, Astronomy and Radio Astronomy.
Radio Astronomy is part of Astronomy.

I suggest that you write a brief article for the Radio Jove Bulletin, describing your activities. I believe Dr. Leonard Garcia, Editor of the Bulletin, will be interested.

Let us learn together.

Thank you for your message.

Hi Victor, John - Here is a chart overlay with John's and my charts from 02 Dec. I do not have an audio recording of the times in question.

Although there seems to be some correlation at certain times, my chart for at least an hour before and after looks very similar and shows what I think are random noise pulses. However, statistical analysis of the raw SPD files may show something. Victor - what do you think?

Happy listening, and watching!

 Solar type III bursts and a Jovian Io-C event, observed from Earth and Space, December 1 2009

STEREO WAVES A and B recorded an initial type III burst, followed by 3 weak low frequency bursts, 2130 to 2300 UT, 200 Khz to 10 Mhz band.

They were followed by an Io-C event, near 23 UT, terrestrial ephemeris CML 356d Phase 261d, 3 to 16 Mhz:

http://tech. groups.yahoo. com/group/ Radio_JOVE/ message/783

We should not expect a close correlation, because of the long distances between the Earth and the STEREO Observatories, in excess of 100 million kilometers.

I would like to collaborate in a closer study of the observations, and perhaps write a short Bulletin article with any interested participants.

I spent a moment processing my audio files from the December 2, 2009,
daytime Io-B period.

There is positive Jupiter at the times noted on observer's charts.  I
have posted a one minute .mp3 sound file of the 2219 UT minute at 21.1
MHz ( file is less than a 1 MB in size).

http://www.heliotown.com/jIoB20091202_2219ut21MHzAsh.mp3

I also posted a file of what I believe to be "false Jupiter" that sounds
a great deal like Jovian emission but I believe it is an unclear
interference-like voice transmission. This is why it is sometimes hard
to verify Jupiter during the daytime ( and nighttime ! ) without
correlation from other observers.

Is it Jupiter?
http://www.heliotown.com/INT_20091202_2140ut.mp3

In any case, it is very neat to receive Jupiter at 3 pm in the
afternoon!  Quite amazing.

Sounds like S bursting at 2137 UT.  21.1 MHz   Probably is Jovian.  Good
stuff actually.

Looks like there is an Io-B pass at 2130-2300 UT.  I will turn on the
radio and see what happens.

Wow, John, you're really pulling it in.  I looked at my chart and thought,
"Oh well, just local interference."

For comparison, my chart for the same time period attached.

RJs:
Picked up a bit of Io-C today.
First period of (weak) activity: 2114 - 2136 UT (CML=296*-303*  &
Phase=247*-248*).
Chart attached for second period of stronger activity 2210 - 2240 UT
(CML=327*-346* & Phase=254*-259*).  Some interference from "sweepers"  etc,
but
fairly good Io - aurally mostly "L" & some "S"  bursts.

I refer to the ISES sunspot number chart updated to October 2009:
http://www.swpc.noaa.gov/SolarCycle/

It does not appear to confirm the May 8 2009 Solar Cycle Prediction Panel consensus prediction. So far, the trend is well below the prediction, and way off the April 2007 predictions:
http://www.swpc.noaa.gov/SolarCycle/SC24/index.html

There is much we do not know about the Sun.
