    #20704 = 90- 54 E = Gorizont 20 aux motor
    
    I estimate that this decayed at Apr 23 22:41 +-90m near 11.6 S, 58.9 E,
    just before a northbound equator crossing over the western Indian Ocean.
    SpaceCom puts decay at Apr 23 22:35 +-1h at 35.0 S, 31.0 E, which lies
    only a little earlier, to the S of Durban, S Africa. 
    
    My estimated elset for the final rev:
    Gorznt 20 aux motor                              259 x 102 km
    1 20704U 90054E   00114.88691442 1.30754265  45526+1  87885-3 0 92243
    2 20704  46.5007 262.9580 0120199 325.0410  34.1758 16.34554991113680
    
    
    #23834 = 96- 19 B = GPS 2-25 Delta 2 rocket
    
    I predict this decay for Apr 27 08:39 +-10h while SpaceCom says Apr 27
    13:08 +-1d. This is a morning object after emerging from eclipse near
    northern apex at 35 deg N. Eclipse entry occurs near 32 deg S in the
    evening sky. the latest elset reads:
    GPS 2-25 r1      5.9  2.4  0.0  5.0 v   12       225 x 213 km
    1 23834U 96019B   00116.55402682  .03134448  14029-5  14868-2 0  8564
    2 23834  35.0396 198.3168 0009687  75.0404 285.1458 16.20235009228513
