[amsat-bb] Mystery Solved - Pass From The Past

Tue Apr 7 22:12:05 UTC 2015

Hello again, John!

I gladly downloaded the data and found some interesting things even in AMSAT's data.

In the 2014 file, AO-73 is identified as object #39444U starting January 16, 2014 and after.

In the same 2014 file, AO-73 is identified as object #39445U on January 9, 2014 and prior.

In the 2013 file, there is some discussion about the actual object number of AO-73 at first. It changes a few times, and settles on 39445.

I know that when a new spacecraft appears it may take a while for the details to settle.

I thought it was interesting and a reminder to check first the object number. :)

73!

Hi Bryan.

Glad to hear you found the source of the problem.

Just as a further confirmation, AMSAT-NA's 2-line elements issued on January 29, 2015 yielded the following predictions for AO-73 (as object number 39444) at your QTH, and match your observations exactly:

predict -t ao-73.keps -q KL7CN_W6-CM98fn.qth -p AO-73 `date -u +"%s" --date="2015-01-29 05:00:00"`
