    #20966 = 90-104 A = Cosmos 2106
    
    The final elset..
    Cosmos 2106      4.0  2.0  0.0  6.2 d   10       153 x 143 km
    1 20966U 90104A   00098.23373669  .29747761 -12866-5  60296-3 0  5403
    2 20966  82.4640  95.9910 0007169 270.9952  89.0532 16.46765361524866
    ..has it running only 1.1 sec early against the prediction I posted
    earlier today. My prediction for the decay is unchanged at Apr 7 09:10
    UTC +-40m near 18.6 N, 60.2 W, putting it just NE of Antigua & Barbuda
    in the NE Caribbean on the southbound approach to an equator crossing N
    of Manaus, Brazil. That orbit took it near Halifax, Nova Scotia, at 
    09:04. Earlier, it made a northbound crossing of central Australia,
    passing over Ayers Rock at 08:25.
    
    My prediction for the final orbit is:
    Cosmos 2106      4.0  2.0  0.0  6.2 d   10       122 x 118 km
    1 20966U 90104A   00098.35495018  .95253804  14471+2  40518-3 0 95405
    2 20966  82.4605  95.8440 0003444 270.4831  89.4774 16.57366409524883
    
    SpaceCom puts the decay further south over the Drake Passage between
    S America and Antarctica at Apr 7 09:33 +-16m near 58.2 S, 50.0 W.
