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: STS-88 1 25549U 98069A 98348.62717112 .00002679 00000-0 33545-4 0 401 2 25549 51.5748 45.0571 0012432 240.6076 219.3764 15.59015940 1626 ISS 1 25544U 98067A 98348.48153770 -.00017891 00000-0 -22746-3 0 1216 2 25544 51.5929 45.7864 0009284 251.2289 108.7692 15.58004098 3791 Does anybody have any ideas?
