The launch of three Glonass satellites, Cosmos 2362/3/4, produced the
following objects:

SpaceCom issued these decay notices for the Proton and the platform,
both of which have already decayed:
Object Notice issued Predicted decay
UTC UTC
#25596 = Cosmos 2362 Proton r Dec 31 01:40 Dec 31 05:29 +-3h
#25596 = Cosmos 2362 Proton r Dec 31 03:53 Dec 31 06:14 +-2h
#25596 = Cosmos 2362 Proton r Dec 31 08:22 Dec 31 06:09 +-37m
#25597 = C 2362 Proton platform Dec 31 07:53 Jan 2 10:23 +-1d
#25597 = C 2362 Proton platform Dec 31 11:33 Dec 31 06:46 +-2h
My own satEvo calculations of the decay times for these are 05:50 UTC
and 08:42 UTC respectively. I show the platform lasting for another
orbit beyond SpaceCom's decay, though the elsets for this appear to be
confused with that for another object. The one elset (so for) for the G
debris object has a drag term which appears too low, and this may have
already decayed also.
