#25769 = 99- 30 B = Starshine This is now into its final 24 hours. My latest prediction is for decay at Feb 18 16:44 UTC +-5h at 20.0 S, 162.7 E while SpaceCom's latest is for decay at Feb 18 17:22 +-6h at 2.2 N, 41.6 W. Against the prediction I posted yesterday, this was running 10 seconds late at the epoch of the latest elset. My new estimate is much more in line with predictions by Harro and SpaceCom - unfortunately, SatEvo has been having difficulty with Starshine's almost perfectly circular orbit. I calculate that the final orbit... Starshine 1.0 0.0 0.0 9.0 d 0.30 131 x 130 km 1 25769U 99030B 00049.66275087 .57054002 49145+1 37361-3 0 93334 2 25769 51.5727 5.1953 0000976 256.7415 103.2477 16.53498915 42127 ...will begin with a northwards crossing of the equator at 15:54 UTC between Brazil and Africa. It crosses NW Africa in daylight from Conakry, Guinea, at 15:57 to Tunis at 16:06. It crosses S Italy to Bucharest, Romania, at 16:10, then Russia to NE China where it passes SW of Beijing at 16:25. It then heads out over the E China Sea and the W Pacific. I put the decay near the island of New Caledonia, to the NE of Australia. If it survives, the orbit then takes it to the N of New Zealand and across the S Pacific to reach Santiago, Chile, at 17:10. The track then curves northwards across S America to another northbound equator crossing off the mouth of the Amazon, Brazil, at 17:21. USSPACECOM places the decay near here. If it survives further, the track takes it across Europe from Madrid, Spain, at 17:35 to Munich, Germany, at 17:38, and just N of Kiev, Ukraine, at 17:41. #25911 = 99- 49 E = Globalstar 33 Soyuz r SpaceCom's final notices are overdue, its last one (issued at 10:25 UTC) being for decay at Feb 17 14:59 +-3h at 27.0 S, 164.4 W. I show decay while this was southbound over SW Africa, to the S of Luanda, Angola, at Feb 17 17:18 +-90m (13.5 S, 13.2 E), If it survived, it might have passed near Johannesburg, S Africa, at 17:22 UTC.
