    No new SpaceCom decay warnings have appeared on OIG's WWW pages, even
    for the Pegasus rocket that has now decayed. My Decay Watch page carries
    my updated notices for the following...
    _____________________________________________________________________
    
    Object: #23210 = 94- 50 H = Cosmos 2287 aux motor
    
    Current decay predictions:
       SpaceCom: Sep 25 15:40 +-2d        26.9 S   102.7 E
       SatEvo:   Sep 26 02:19 +-10h       26.0 S   148.3 E
    
    Latest elset:
    Cosmos 2287 aux motor                            1263 x 96 km
    1 23210U 94050H   00268.55495993  .30373503  00000-0  49432-3 0  7055
    2 23210  63.9358 359.7905 0826644 206.9779 148.5881 14.64340936102404
    
    The latest elset shows this running 1.9 min early against 
    yesterday's prediction. I predict that this will decay near perigee
    on the predicted orbit...
    Cosmos 2287 aux motor                            258 x 89 km
    1 23210U 94050H   00270.06112332 2.31328795  10678+2  98284-3 0 97054
    2 23210  63.8740 354.6369 0128955 206.7847 152.5436 16.37105059102633
    This puts it southbound over Queensland, Australia.
    _____________________________________________________________________
    
    Object: #25737 = 99- 26 C = Terriers Pegasus rocket (stage 3)
    
    Decay analyses:
       SpaceCom: Sep 24 08:24 +-1d        76.3 N     7.8 E (dated 22nd)
       SatEvo:   Sep 24 00:39 +-45m       14.1 S   157.8 E
    
    Final elset:
    Ters Peg stg3    1.3  1.0  0.0  7.5 d  1.1       141 x 138 km
    1 25737U 99026C   00267.96898848  .21188268  00000-0  27156-3 0  5328
    2 25737  97.5533 168.6995 0002242 207.1717 153.0160 16.49824944 76681
    
    The final elset has this running 7 sec early against my final
    prediction. I estimate that this decayed while northbound over the Coral
    Sea to the NE of Australia near the end of the orbit given by this
    elset.
