While waiting for IGS 1B I spotted 88-93A Cosmos 1975 (uninteresting) and while observing Raduga 33 I saw a -tive magnitude flare from 88 102A Cosmos 1980 below the Andromeda galaxy. Raduga 33 was visible at mag -2 .. 1-power .. 7x50 for 56 minutes, with some 15 minutes when I didn't find it in-between. The stopwatch was running continuously this time, and analysis with 'synodic' showed there was NO phase shift, so I will have to modify my rotation model. The flash period decreased quite abruptly early in the "dark age" from 33.324 to 33.236 s. Several 1/4 and 3/4 period flashes (no mid-period) were seen. PPAS when I have checked the total/end times and period count.

But which? The last one had a 7+ second error - I assume it was a transcription error 49.42 <- 42.42 , now corrected. ----------------------------------------------------------------- To unsubscribe from SeeSat-L, send a message with 'unsubscribe' in the SUBJECT to SeeSat-L-request@satobs.org List archived at http://www.satobs.org/seesat/seesatindex.html
