Today we have now the decay information for the SL-12 R/B (Aux Motor):
                Dec 19, 13:50 UTC +/- 3 hours (42.7°N, 30.9°E)
Well within the limits of Alans last prediction, a few hours later then my 
estimate.
The next candidate 1997-084J - Pegasus R/B shows a normal behavior. 
MPM gives a a decay on    Dec 28 04:50 UT  in good agreement with USSPACECOM
and also SatEvo. The SGP4 analytical method shows a tendency to an earlier 
reentry in the second half of Dec 27.

Don't forget 1996-69A (SSC 24670)! SPG4 shows an decay date at
                      Dec 31 06:15 UTC 
That is significantly to early. But I think it could be possible that the EORSAT
may be decay around Jan 5-8, 1999.

By the way: The just released OIG Sixty Day Forecast Report give the following
decay dates:  Pegasus R/B: Dec 23  and Cosmos 2335  also Dec 23 ! 
No commentary!!
