OIG appears to have been unreachable since ~noon UTC today, so I have no
word on the final elsets for #25499, the decaying auxiliary motor from
the Cosmos 2350 Proton launch. The failure also means that there are no
elsets yet for the two new Iridiums that were launched today by a
Chinese Long March rocket (launch was at 11:30 UTC).

Another decay notice was published by OIG before it went AWOL:

Object                            Notice issued    Predicted decay
                                       UTC              UTC
#25499 = C 2350 aux motor         Dec 19 00:43     Dec 19 10:56 +-7h

The latest (final?) elset is:

C 2350 Prot deb (aux motor)                      944 x 94 km
1 25499U 98025E   98353.36489583  .02420477  93517-5  29501-4 0  1356
2 25499  47.2036 205.0145 0616251  85.2847 278.1724 15.15594482  6017

The drag term is far too low, but the elset appears to show it running
12 minutes early against the prediction I posted yesterday. My own
prediction following receipt of this elset was for decay at December
19.44 (10:39 UTC) or possibly one orbit later.
