I wanted to see what passes I might have for ARISSat-1, and used the pass
prediction utility on the AMSAT web site.  I'm at the office, and don't have
my personal laptops with their tracking programs handy.  It is now showing
only 3 more passes, two tonight and one at 1555-1600 UTC tomorrow.
Even if I chose to see the next 50 passes, I only get data for these 3

Space-Track.org has a "TIP message" from a few hours ago predicting a
decay time of 0534 UTC tomorrow +/- 11 hours.  I suppose that is
consistent with what I saw from the pass prediction utility on the AMSAT
web site.  Time is running out.......
