From: Mark Hanning-Lee <markhl@prodigy.net> To: SeeSat-L@satobs.org Subject: Recent obs Date: Fri, 3 Jan 2003 18:58:37 -0800 (PST) 2002-12-30 5:40:49 PST = 2002-12-31 13:40:49 UTC solar panel flare from Iridium 51 ? reached only mag 2 instead of predicted mag -3. I find that solar panel flare predictions from iridflar are usually quite good, and in fact a solar panel flare from Iridium 35 reached the predicted magnitude about 1 minute earlier. The iridium flare program outputs the predicted magnitude value based on the orientation value used by the program. If the satellite is off in orientation from what the program uses, the the magnitude seen can be fainter or brighter. 12/30 18:28 PST = 12-31 2:28 UTC predicted mag 4.7 14402 Cosmos 1503 r. Candidate for a mag -1 flash 10 deg below, 1 deg right of bottom right star of Cassiopeia. However the position was not quite right: this object was about 4 deg further left than the observed flare. Any other candidates? If you mean bottom right star of cassiopeia, as being alpha cas, I get Cosmos 1903 r ( 18704 ) close by. 12/30 18:38 predicted mag 4.7 18749 Cosmos 1908 r passed southbound through square of Pegasus at about mag 2, about 1 min earlier than predicted. A good match except for the time discrepancy. Assuming you are at 33.72900 N 117.82200 W I don't get Cosmos 1908 r passing through the square of pegagus at the time given, but passes left of the star Alp And which is one of the stars I call in the square of pegagus. Now to wait for other people's results.
