Here's a PPAS format report: > > 96- 4 B 00-07-11 04:39:39 EC 161.4 0.5 19 8.50 Here are my most recent observations of that sat : 96- 4 B 00-06-12 00:55 MJ 360.2 0.3 49 7.3 A'A' mag 5 --> 8 96- 4 B 00-06-26 22:42 MJ 356.6 0.2 45 7.9 A'A' mag 6 --> 8 The rotation seems to be decreasing. The three observations match very well : the rate of my 2 observations is 0.04"/d and the rate between Mike's measure and my second one is 0.02"/d > The last object we observed, Iridium 920 (24871, 97-34C; formerly > Iridium 20) was tumbling very rapidly, on the order of twice per > second. I spotted that sat last year and more recently in June 2000 : 97- 34 C 99-06-16 22:18 MJ 39.8 0.2 40 0.99 AA 97- 34 C 99-06-21 22:48 MJ 50.7 0.2 50 1.014 A'A' 97- 34 C 99-06-22 22:14 MJ 123.1 0.2 120 1.026 F'F' 97- 34 C 99-07-01 22:09 MJ 102.6 0.2 100 1.026 AA 97- 34 C 00-06-12 00:01 MJ 1.06 T=124.08,err=0.02,F'F' Maybe, I measured a double period (with binocs 7x50)?
