    With the benefit of subsequent observations, I believe that
    the situation is clear.  I believe that the leading object (A)
    maneuvered about Dec 10 at 0330 UT and the trailing object (B)
    made a very similar maneuver about 1500 UT.  The amount of the
    maneuver was about 50 seconds per day.  The A object was ahead
    of the B object by about 29 seconds before the maneuvers and
    about 53 seconds after the maneuvers.  The fact that the
    maneuver of about 50 seconds was about 1/2 day later for the B
    object caused it to lose 24 seconds so that it went from 29 seconds
    behind to about 53 seconds behind.
    
    The following elsets fit the available observations:
