    Decay predictions:
       SpaceCom: Sep 22 04:15 +-15h       23.6 N   178.3 W
       SatEvo:   Sep 22 05:16 +-5h        22.6 S    80.1 W

    The latest elset shows this 8 sec late against yesterday's prediction. I
    show this decaying while southbound over the Pacific just to the W of N
    Chile on the second of these predicted final revs:
    Palapa B2 r                                      131 x 119 km

    The latest elset shows this running 9 sec late against yesterday's
    prediction.

    Object: #25995 = 99- 68 B = Terra Centaur rocket
    
    Decay predictions:
       SpaceCom: Sep 21 14:00 +-2h        13.0 N   171.8 E
       SatEvo:   Sep 21 13:23 -15m+45m    61.1 S    13.4 W
    
    Final elset:

    The final elset shows this running 11 sec late against yesterday's
    prediction. SpaceCom has yet to post its final decay analysis. I
    estimate that this decayed while southbound over the far S Atlantic on
    the orbit given by this elset.
