Other than the SpaceCom decay notices for the decayers from the Glonass
launch, which I reported in another posting, the following notices are
current or have been released since my last update.

Cosmos 2335 was running 25 seconds late against yesterday's prediction
at 98365.58. I now predict decay for December 31.99 (23:50 UTC +-2h),
which is one orbit earlier than does SpaceCom, and 70 minutes later than
Harro in the MPM prediction in his latest posting. My prediction would
place it near 60 deg S, 120 deg E, south of Australia and moving towards
Syndey.
