Hello all,
I have a rather unusual question: can anyone tell me what satellite was visible over JM49MG around 20.20 UTC of 06 Jan 2009? I have in my log a contact via VO-52, but I received a QSL for that same contact via "AO-07 orbit 56249". I tried with my predict program but with current keps it gives result not meaningful for 06 January 2009. Thanks in advance

Frank,
I simulated that time on Orbitron ( 06 January 2009, 20:20 UTC), and according to Orbitron, neither AO27 or VO52 were over your QTH at the time. I am sending you the screenshot of that particular time via a different email message.

But did you use keps from that time period? Today's keps won't work.

My impression of the 'simulate' feature of Orbitron was that it would automatically retrieve the old keps..... At least it never gave the the option of using the old. Maybe I imagined it better than it is. Could an Orbitron guru correct me?

If it's like every other tracking program I've ever used, it overwrites the old keps each time you update it. You're not given the option to use the old ones because they're not there anymore.

Which begs the question, where can one find archived keps? AMSAT does not archive the KEPS mailing list, so unless someone on here is a subscriber and has keps bulletins from that far back, where else can you look?

George,
Try Celestrak: www.celestrak.com.
There is a link to historical data. There's a lot there, but the administrator, T.S. Kelso says that the full archive would be too large to store on line, so if you need something that's not there you can submit a special request.
Haven't tried it yet for Historical data, but Celestrak is a good site for current keps & lots of other interesting stuff.

Aa a matter of fact, I have Keps going back several years, because I tend to archive my mail. Might be useful for historical studies like the one in this thread.

If someone needs them, I have keps from 2005 up to recent. I have ARRL keps starting with March of 2005 and Amsat starting with April of 2005.

Reid, W4UPD

Hi!

Space Track also has archived keps. Log in, search by satellite number, then specify the date or date range instead of taking the latest set or the last 5 sets. Very useful for something like this.
If you are interested in the AMSAT sets specifically, or don't want to sign up for a Space Track account, the weekly sets from the AMSAT KEPS list are archived since August 2006 when AMSAT moved to new mailing- list software. Go to:

Hi Frank,
I used the keps from January 2009 and set the PC clock to this date - it was HAMSAT VO-52. AO-7 was near Australia at this time.
