SpaceCom has issued the first decay warning for #25088 = 97- 79 A =
Cosmos 2347, predicting its decay for Dec 11 16:07 UTC +-2d. My own
analysis yields Dec 11 18:14 +-17h. This suffered an explosion about 10
days ago and I do not know how much of the original satellite remains as
97-079 A. It enters eclipse in the Earth's shadow at 63 deg N latitude
as it approaches northern apex at ~16:30 local time. It leaves eclipse
while southbound near 44 deg S at ~02:30 local time.

SpaceCom appears to have temporarily lost #25923 = 99- 52 B = Telstar 7
Ariane 44LP r for which no elsets have been issued for 39 hours.
SpaceCom's last estimate was for decay at Dec 8 17:48 +-2d, so this may
be already down. On the other hand, I predict the decay for Dec 12 +-2d.

There are more details and predicted elsets for both decayers on my
