The latest elsets for these decaying rockets are:
C 2358 Soyuz r   6.0  2.0  0.0  5.0 d            244 x 151 km
1 25374U 98038B   98178.66825496  .04906349  60295-5  44422-3 0   271

These put them 26 and 19 seconds late respectively against the
predictions I posted yesterday.


I now predict the decay of the Cosmos 2358 rocket at about June 28.7
(17:15 UTC +-5h). SatEvo elsets:
