    2000-049B (#26478) Raduga 1-5  Proton RB
    
    SpaceCom's FINAL REPORT - prepared August 31, 02:15 UTC - shows the decay on
                     30 August, 21:57 UTC +/- 02 hours (33.0°N, 0.1°E)
    on a northbound pass over NW Africa (Algeria).
    
    MPM + REENTRY delivers with the last two ELSETs 00243.541... and 00243.723...
    the decay on     30 August, 21:52 UTC +/- 11 minutes ( 19.28°N, 346.40°E)
    on the same pass also over NW Africa (Mauretania).
    
    As Alan mentioned yesterday SpaceCom produces a lot of confusion with an
    object #26479 - the Proton Platform. In a FINAL REPORT - prepared August 31,
    02:15 UTC - they shows the decay on
                     30 August, 22:20 UTC +/- 03 hours (29.8°N,116.5°E)
    on a descending pass over China.
    
    But this object is a "ghost". The real platform decayed - that's my estimate -
    on August 29, early morning (UTC). All Proton platforms are shortliving objects
    and decays much earlier then the Proton 3. stage.Some the earlier und later 
    released ELSETs are clearly related to #26478, the RB.
                                      Epoch             ndot             MM
    The last ELSET for # 26478:       00243.72354432    0.12216401       16.48625990
    The penultimate ELSET for #26479: 00243.72348124    0.12400761       16.48641625
    
    A special ELSET comparison program with an output of TCA (Time of Closest 
    Approach), Midpoint and Epoch shows the identity of the ELSETs for the two 
    objects. The deviation is only in the order of 3.93 km.
    Based on the released ELSETs 00243.541... and 00243.723... for #26479  MPM +
    REENTRY shows the decay on  
                         30 August, 21:54 +/- 11 minutes (25.45°N, 351.11°E)
    on a northbound pass over NW Africa. This is practically identical with my 
    prediction for the RB (#26478). SpaceCom's two objects are really only one.....
