    The 7 day old elements were based in part on Bjorn Gimle's obs of 2005 Jan 6, of
    an object he believed was 96072A, but which I suspect may have been MSX (96024A
    / 23851). I am not certain, because there is a substantial time and track error
    relative that object also. Perhaps a reduction error?
    
    Using Greg Roberts' obs of 2004 Dec 14 and Russell's of 2005 Jan 13, I obtained
    the following 96072A elset:
    
    USA 129         15.0  3.0  0.0  5.3 v
    1 24680U 96072A   05013.82245905  .00014087  00000-0  19496-3 0    03
    2 24680  98.0039  78.9119 0518857 297.4661  57.4704 14.74158695    02
    
    Residuals are small.
