>He said brighter than Jupiter... (which is brighter than -1). The magnitudes mentionned by my programs are, of course, calculated according to the STANDARD magnitude. Don't you know that Iridium 4 can give a much brighter magnitude in some circumstances? I maintain "It should be". Here is another way to give informations on that passage: (Please forget the calculated magnitudes) IRIDIUM 4 1 24796U 97020E Ref.Date: 1997 233.12287546 = 21 / 8 / 1997 n=14.34215898 Height.: 771- 778 Km Magnit.St.: 6 31/ 8/97 Az.: Alt.: Sun: Hgt.: Dist.: Magn.: Alpha: Delta: Const.: 2h60m 0s 10d 22d -12d 772Km 1637Km 6.3 4.0h +71.9d Cam 3h 1m 0s 16d 32d -12d 772Km 1299Km 5.8 1.4h +75.6d Cas 3h 2m 0s 29d 46d -13d 772Km 1020Km 5.3 22.1h +67.0d Cep 3h 3m 0s 65d 61d -13d 772Km 865Km 4.9 20.7h +44.1d Cyg 3h 4m 0s 124d 57d -13d 772Km 898Km 5.0 20.1h +15.9d Sge 3h 5m 0s 149d 41d -13d 772Km 1104Km 5.5 19.8h -6.5d Aql 3h 6m 0s 159d 28d -13d 772Km 1408Km 6.0 19.6h -21.3d Sgr 3h 7m 0s 164d 19d -14d 771Km 1759Km 6.5 19.5h -31.2d Sgr 3h 8m 0s 167d 12d -14d 771Km 2134Km 6.9 19.4h -38.3d Sgr 3h 9m 0s 169d 7d -14d 771Km 2520Km 7.3 19.3h -43.8d Sgr 3h10m 0s 170d 3d -14d 771Km 2912Km 7.6 19.3h -48.3d Tel My pleasure, avec plaisir, Alphonse alphonse.pouplier@skynet.be URL:http://users.skynet.be/alphonse/ To be on my list: Send "subscribe alphonse" to listbot@interlink-bbs.com Main coord.: Wepion (Belgium) +50d25m27s 4d51m42s East Aux. coord.: Esparron de Verdon (France) +43d44m19s 5d58m12s East
