SpaceCom has yet to update its erroneous decay prediction for Soyoz rocket, but has produced the first decay warning for the Cosmos 673 rocket. -------------------------------------------------------------------- Object: #25665 = 99- 15 B = Progress M-41 Soyuz-U r Decay predictions: Source Prediction made Predicted decay at Latitude Longitude UTC UTC deg deg SpaceCom Apr 2 18:19 Apr 4 04:59 +-21h 39.0 N 122.8 W SpaceCom Apr 2 22:18 Apr 3 16:37 +-11h 25.3 S 95.7 W SatEvo Apr 2 19:45 Apr 5 02:25 +-1d SatEvo Apr 2 23:15 Apr 4 09:58 +-12h 49.1 S 45.4 W SatEvo Apr 3 20:45 Apr 4 12:05 +-6h 51.7 N 72.7 E Latest elset: Prog M-41 Soyuz r 192 x 167 km 1 25665U 99015B 99093.75862896 .05738858 12314-4 69666-3 0 153 2 25665 51.6283 5.3325 0019230 75.4919 284.8778 16.34831279 210 SatEvo predictions: Prog M-41 Soyuz r 181 x 160 km 1 25665U 99015B 99094.00284717 .08320266 41121-1 68810-3 0 90159 2 25665 51.6273 3.9586 0016518 76.5174 283.6666 16.38327845 253 Prog M-41 Soyuz r 165 x 148 km 1 25665U 99015B 99094.24647036 .13684124 13766+0 45968-3 0 90155 2 25665 51.6259 2.5799 0012985 77.5466 282.5986 16.43409926 291 Prog M-41 Soyuz r 142 x 131 km 1 25665U 99015B 99094.42852046 .37462005 16407+1 33362-3 0 90153 2 25665 51.6236 1.5409 0008289 78.3224 281.7706 16.51115302 322 Prog M-41 Soyuz r 118 x 112 km 1 25665U 99015B 99094.48891790 1.41420034 50000+2 41572-3 0 90150 2 25665 51.6214 1.1924 0004323 78.5826 281.4659 16.59227629 330 Note: The latest elset has this running only 0.3 second late on the prediction I posted in yesterday's update.
