    I have scrapped my epoch 03365.48661053 elset of 03054A, with mean motion
    13.40602325 rev/d, reported here:
    
    http://satobs.org/seesat/Dec-2003/0390.html
    
    Subsequent observations were late relative that elset. Adding 1 s to Tony
    Beresford's observation of 2003 Dec 31 at 12:47 UTC corrects the problem.
    
    The following elements reveal that as of early Jan 01 UTC, 03054C's ascending
    node trailed 03054A's by 9.5 s, closing at the rate of about 0.16 s/rev.
    
    I suspect that when they are 6 to 8 s apart, one or both will manoeuvre to match
    mean motions, stabilizing their separation. That would put the earliest
    manoeuvre time at about Jan 01.708 UTC, and the latest about Jan 02.641 UTC.
    
    I still believe that their planned mean motion is about 13.4044 rev/d, but they
    may remain near 13.4060 rev/d for some time, until they arrive at some optimal
    phasing relative the other operational NOSS groups.
