#23834 = 96- 19 B = GPS 2-25 Delta 2 rocket Only two elsets appeared over the final 18 hours of this object's life, and the first of these, for epoch 00117.96 looks suspect and was ignored in my analysis.

I show this decay over the SW Indian Ocean at Apr 27 13:29 UTC +-4h near 34.0 S, 52.3 E. This places it to the SE of Madagascar as it tracked north- eastwards towards an equator crossing over Indonesia. SpaceCom has it decaying a little earlier while southbound over the S Atlantic at Apr 27 13:18 +-20m and 21.8 S, 16.0 W. There would have been a pass across the USA from the N of Los Angeles at 12:45 UTC to the S of Houston at 12:50. #26302 = 00- 21 B = Progress M1-2 Soyuz rocket The final elset... PrgM1-2 Soyuz r 6.0 3.0 0.0 5.0 d 15 142 x 133 km 1 26302U 00021B 00118.36140886 -.22136931 12917-4 -21600-3 0 189 2 26302 51.6341 157.5397 0006686 138.6205 221.3316 16.50689078 258 ... has this running 2.4 seconds early against the prediction I posted earlier today. However, the negative drag leads me to treat it as suspect so that I hold to my earlier analysis that this may have decayed near a southbound equator crossing off the NE coast of Brazil at Apr 27 10:51 UTC +-90m at 41.5 W. A little earlier it crossed eastwards over N America, passing N of Vancouver at 10:30 UTC, N of Minneapolis at 10:35, over Detroit at 10:37 and Washington DC at 10:39. SpaceCom's analysis places the decay close to Detroit (Apr 27 10:42 +-55m at 41.9 N at 82.9 W) but the 55 min uncertainty suggests that it was not tracked on that orbit. My SatEvo prediction for the final two revs was: PrgM1-2 Soyuz r 6.0 3.0 0.0 5.0 d 15 149 x 138 km 1 26302U 00021B 00118.36145331 .33648245 11013+1 46997-3 0 90171 2 26302 51.6286 157.5487 0008616 89.8790 270.2197 16.48409667 258 PrgM1-2 Soyuz r 6.0 3.0 0.0 5.0 d 15 131 x 124 km 1 26302U 00021B 00118.42197323 .75665394 54183+1 42145-3 0 90172 2 26302 51.6270 157.2012 0005552 90.1384 269.9252 16.54392913 262 See http://www.wingar.demon.co.uk/satevo/dkwatch/ for more.
