    The following elements are based on observations by Tony Beresford and Greg
    Roberts from 2000 Nov 19 - 24:
    
    USA 129         15.0  3.0  0.0  5.1 v
    1 24680U 96072A   00329.86038194  .00041292  00000-0  58706-3 0    07
    2 24680  97.8757  30.1012 0469845 176.2465 184.2835 14.83953062    01
    
    Mean residuals are about 0.02 deg.
    
    The possible major re-boost manoeuvre had not occurred as of Greg's observation
    on Nov 24, at 20:27 UTC.
    
    It now seems unlikely that the KeyHoles will manoeuvre at the current
    opportunity, but since I don't know the exact tolerances (in terms of allowable
    distance of perigee from equator), I am continuing the alert a bit longer.
    
    I expect the next re-boost opportunity to occur on or about 2000 Dec 03, when
    USA 116's argument of perigee crosses the equator.
