    Bob Christy has reported radio observations on two consecutive passes, early on Jan 21 UTC, which
    lead me to believe that the initial orbit is similar to that of USA 186, after its launch in Oct
    2005. Here are revised elements:
    
                                                            163 X 1027 km
    1 72001U          11020.92423331  .00988049  00000-0  77000-3 0    09
    2 72001  97.9000 135.1447 0620000 185.0000 174.4842 14.90000000    08 
    
    The elements remain fairly rough, so significant time and track errors should be expected.
    
    Next step will be to raise perigee by about 100 km. My guess is that will occur within range of
    Diego Garcia, on Jan 22 near 19:14 UTC or 20:49 UTC.
