NASA says it continues to wait for final confirmation of re-entry. If debris
fell on land (and that's still a BIG if), Canada is most likely area, the
space agency just said.

That's incredible that NASA still is not sure with precision where the sat
fall down!!

Although I have severely limited satellite visibility I have been copying
telemetry from ARISSat1 for some weeks. I live in a valley surrounded by chalk
hills and cliffs over 100 metres higher than me so my visible horizon is +12
degrees to +18 degrees at best. Also my 3+3 element short
Hi Dick,
I think the delay is the result of the timer circuit that was mandatory for its
release during the spacewalk from the ISS. The delay timer had to be there,
and there is no way to defeat it, so it just has to run its course every time
it exits eclipse.
As you have probably noticed,
Did not catch the second voice digit! MET is One shh But satellite is
switched on.
On 18 september the voice announced MET (19 and 21) equalled the time in
sunlight, as I have calculated back using today's keps, within 1 minute.
Allowing for keps 1 week old I think the MET is in fact

NASA's decommissioned Upper Atmosphere Research Satellite fell back to
Earth between 11:23 p.m. EDT Friday, Sept. 23 and 1:09 a.m. EDT Sept. 24.

It is not an uncertainty. A large satellite can break up and different pieces
can re-enter at different times. I experienced this working the orbital decay
of the Apollo 9 Lunar Module back in 1981.
FYI Apollo 9 did a lunar landing rehearsal in Earth orbit.

All,
Now that everybody has climbed out from under their beds, it might be a good
time to think about entering the ARISSat-1 Chicken Little Contest. We are
still looking for calculations/guesses/darts-in-the-calendar submissions for
when ARRISSat-1 makes its final orbit. We have a fair number
ARRISat-1 was in pretty good shape when it finally
turned on after being in eclipse this morning around
1510z or so. I had a good qso with WB0KFC and heard
someone else (maybe N8MH?) at the end of the pass. The
bird went off the air around 1516z before my LOS.
The next pass at 1643z should be
Based on posted observations, I have come to the conclusion that the
satellite's MET comes up at either 0 or 1 when the satellite turns on, after
the 10-or-so minute delay after entering sunlight. Depending on what mode it
thinks it should be in, I suppose it's possible that it might in fact
Interesting
My observations last weekend show that MET matches the satellite entering
sunlight:
18 September
calculated Time into sun: 1004 utc
Time of obs (announcement): 1023 utc
Voice announced MET: 19
calculated Time into sun: 1136 utc
Time of obs: 1158 utc
Voice announced MET: 21
John K8YSE, thanks again for the QSO on ARISSat-1 today. They're not easy, but
it can be done. That's my third on the bird.

It was a pleasure working some of you this week from the grids
mentioned in the subject line. I also operated from DM83, EM14, and

It is very apparent that DM83 is much more rare than any other grids I
