    #26478 = 00- 49 B = Raduga-1 5 Proton r
    
    Final decay analyses:
       SpaceCom: Aug 30 21:57 +-2h        33.0 N     0.1 E
       SatEvo:   Aug 30 21:50 +-2h        22.2 N    11.1 W
    
    Final elset:
    Raduga-1 5 Proton r                              147 x 139 km
    1 26478U 00049B   00243.72354432  .12216401  12724-4  17286-3 0   174
    2 26478  51.6407 278.1305 0005679 332.2891  27.7790 16.48625990   319
    
    Apologies for listing some recent decay predictions by SpaceCom as being
    for the 31st when they were for the 30th. SpaceCom seem to have remained
    confused about the identity of this object and tracked one object,
    probably the rocket, under two identities - the rocket and the
    "platform". Except for a few early elsets, which were for the quickly-
    decaying platform, all the other elsets issued for both objects probably
    refer this one object. SpaceCom continued to post similar (but not
    identical) decay predictions for both identities to the bitter end. The
    final one posted for #26479 reads...
           SpaceCom: Aug 30 22:20 +-3h        29.8 N   116.5 E
    
    My predicted elset for the final equator crossing is:
    Raduga-1 5 Proton r                              113 x 111 km
    1 26478U 00049B   00243.90492453 2.63047242  50000+2  65241-3 0 90172
    2 26478  51.6379 277.0867 0001651 333.0676  26.9238 16.60606887   343
    I agree with SpaceCom in placing the decay over NW Africa following 
    a northbound equator crossing off the NE coast of Brazil.
