Hello Tristan, Alain, readers;

SatAna/SatEvo propagation gives 11 july 2015 (today) at 21h 59' UTC +- 2
hrs. Here two final derived elsets:

SL-8 R/B                                         148 x 135 km
1 12389U 81033B   15192.80048316  .23566401  60841+0  29556-3 0 99990
2 12389  82.8397  77.3538 0009781 153.7327 206.3170 16.49319806770356
SL-8 R/B                                         136 x 127 km
1 12389U 81033B   15192.86109320  .39966744  17049+1  29646-3 0 99993
2 12389  82.8384  77.2839 0007073 153.4743 206.5619 16.53038958770368

And GMAT propagation using 1435 Kg of mass, Cd of 2.2, Drag area of 14.4,
and propagating with PrinceDormand78 with JGM-3,MSISE90 and current KP
index, gives a 80 Km altitude pass the 11 Jul 2015 at 22:04 UTC.

Data can be found here: http://www.astronautix.com/lvs/kos1k65m.htm

This means that it should have re-enterd atmosphere some minutes ago, or
its about to re-enter in next minutes.

I think Ted could be interested on those recordings/photographs.


Jon.
