On April 26th, around 21:12 UTC I observed a violently flashing satellite= (period about 1-1.5s, maybe 2 magnitudes brightness difference) while waiting for JERS. Analysis of the track led me to conclude that it might = have been USSPACECOM 6677 (73037 C). Several days later, I observed it again (under adverse conditions) and was not clearly able to confirm the = flashing. Observing position was 54.456N, 9.622E, 25m ASL. My questions: = Can anyone confirm the flashing? Depends the visibility of flashes on th= e angle sun-satellite-observer? This evening, May 7, around 20:52 UTC, while waiting for Cosmos 2313, my = attention was drawn to an easily visible satellite (around magnitude 1.6 = at RA 16h31m, Decl 22=B012') that seems to be USSPACECOM 24670 (96069 A).= Using the formula given in QUICKSAT.DOC that evaluates to a standard magnitude of about 2m, so this might be an easy to catch satellite. I'd like to get a confirmation on this observation, too. Observing position was 54.317N, 10.133E, 30m ASL. What kind of satellite are those two? Greetings, Marco
