    alan: do you have an estimated decay date for 22925?
    thanks,

    Summary from my updated Decay Watch page...
    
    _____________________________________________________________________
    
    #14693 = 84- 11 E = Palapa B2 r (PAM-D)
    
    I still predict this decay for September 24. SpaceCom has not updated
    its prediction for decay on the 9th.
    
    Palapa B2 r                                      234 x 175 km
    1 14693U 84011E   00256.18689780  .00568497 -79834-5  13217-3 0  7987

    _____________________________________________________________________
    
    #25310 = 98- 23 E = Globalstar 6 Delta 2 rocket
    
    Current decay estimates:
       SpaceCom: Sep 17 06:02 +-2d        50.8 S    15.5 E
       SatEvo:   Sep 18 17:55 +-1.8d

    _____________________________________________________________________
    
    #26491 = 88- 81 F = GStar 3 Ariane 3 deb
    
    Current decay estimates:
       SpaceCom: Sep 14 20:40 +-2d         0.9 N    72.7 W
       SatEvo:   Sep 18 06:20 +-3d
    
    Latest elset:
    GStar 3 Ariane 3 deb F                           1161 x 175 km
    1 26491U 88081F   00256.17822881  .06795049 -24800-4  72533-2 0    56
    2 26491   7.4334 244.2658 0700263 241.7374 111.0359 14.67864387 49302
    
    I do not know whether this newly catalogued debris object would be
    observable, though the fact that SpaceCom has posted a decay notice
    suggests that it might be large enough. Eclipse entry occurs northbound
    near 6 deg N in the evening and it leaves eclipse near its southbound
    equator crossing in the morning. Only a short span of elsets is
    available, so the prediction is uncertain.
