 Hello everybody,

  Just had my only (and probably last) chance to watch the STS-88 cross the
sky. I'm not good at estimating magnitudes, but my guess would be mag +0.5.
I watched it until it hid behind a building.
  But what caught my eye was a UFO (Unidentified Flying Object, not flying
saucer) my friend saw about 7-8 degrees below ISS. I guess ISS had mag +0.8,
and according to my friend's words, the UFO must have been mag +1 to +1.5. I
couldn't watch it, when my friend warned me, both hid behind the same
building the STS-88 had hid 1 minute before. My father also saw it, though.
This was at 22:12 UTC.
  I was using these elsets:

  Does anybody have any ideas?
