    Observation arc 2004 Mar 23.81 - 24.90 UTC:
    
    USA 129         15.0  3.0  0.0  5.3 v
    1 24680U 96072A   04084.88880779  .00019819  00000-0  30106-3 0    09
    2 24680  97.9618 146.2329 0523946 166.4714 195.1186 14.71262931    04
    
    WRMS residuals = 0.014 deg
    
    The short observation arc to-date suggests that the eccentricity has decreased,
    raising the mean perigee height to about 293 km relative Earth's mean radius of
    6371 km. There is historical precedent for such a manoeuvre, so the result is
    believable, but further tracking is required to be certain.
    
    I was clouded-out last night, and tonight and tomorrow are unlikely to be
    better.
