    Final decay analyses
       SpaceCom: Aug 23 07:09 +-1h        35.4 N   146.8 E

    Final elsets:

    The latest elset shows it running 8 sec late against the prediction I
    posted yesterday. I show this decaying near a southbound equator
    crossing over the E Pacific. This is more than one orbit later than
    SpaceCom's estimate. My predicted elsets for the final two revs:
    GPS 2R-4 Delta 2 r1                              162 x 116 km
    1 26361U 00025B   00236.28311619  .46003903  11211+1  29642-3 0 92200
    2 26361  37.5997 157.8615 0035204 280.9624  78.6417 16.50221777 15656
    GPS 2R-4 Delta 2 r1                              134 x 106 km
    1 26361U 00025B   00236.34351897  .82567895  45350+1  25970-3 0 92205
