IGS 1B flare, no Perseids
This all made me miss the Perseid meteor maximum. During the clearings however, I did manage to catch Lacrosse 2 (91-107A, in twilight), and the failed Japanese satellite IGS 1B (03-009B).
The latter was very bright (about +0.5) in the southeast and east. It then faded notably to +3, +3.5 just past east, and finally flared brightly to -1.5 in the northeast around 21:03:55 UTC.
I got three images of both satellites, totalling 11 positions (I dropped the faint trail end of the third IGS 1B image). The three IGS 1B images showed a second, very faint trail as well, which turned out to be the classified research MSX satellite (96-024A).
