    1 24680U 96072A   03007.58006564  .00030323  00000-0  33622-3 0    01

    WRMS error = 0.009 deg
    
    The object's perigee-crossing of the equator has passed without a manoeuvre. It may be that one of the two eastern-plane satellites
    will set the manoeuvre date. 95066A / 23728's perigee will cross the equator on 2003 Jan 12 UTC; 01044A / 26934 will do likewise on
    2003 Jan 22 UTC.
    
    By the end of January, 96072A's mean motion will have exceeded the highest value in its history, so a manoeuvre is virtually certain
    this month.

    The SRP effects on the rate of decay continue about as expected.
