    following decayers...

       SpaceCom: Sep 22 04:11 +-1h        17.6 S    29.8 E
       SatEvo:   Sep 22 04:07 +-40m       21.7 S    19.2 E
    Final elset:
    Palapa B2 r                                      133 x 122 km

    The final elset shows this 10 sec early against yesterday's prediction.
    I show this decaying while northbound over Namibia in southern Africa.
    My prediction for the start of the final rev:
    Palapa B2 r                                      123 x 116 km
    1 14693U 84011E   00266.11994114  .30434915  17558+1  10451-3 0 98505
    2 14693  28.1163 130.4599 0005990 249.8594 110.0762 16.57577649913255
    _____________________________________________________________________
    
    Object: #23210 = 94- 50 H = Cosmos 2287 aux motor
    
    Current decay predictions:
       SpaceCom: Sep 25 21:44 +-2d        55.5 S   109.6 W
       SatEvo:   Sep 26 04:08 +-1d
    
    Latest elset:
    Cosmos 2287 aux motor                            1921 x 109 km
    1 23210U 94050H   00266.49878615  .18460774  11900-4  66950-3 0  6839
    2 23210  63.9847   5.6980 1225304 206.2899 147.0711 13.65814533 99950
    
    This enters eclipse while northbound near 54 deg S at ~20h local time
    and leaves eclipse near 45 deg N at ~02h local time, also while
    northbound.
