    Some time between Feb 10 and 13, 05004A, manoeuvred to decrease its RAAN
    relative 05004C. They are now nearly 0.15 deg apart in RAAN; their final
    operational separation is likely to be near 0.2 deg.
    
    The Centaur, 05004B, appeared to have significant orbital acceleration during
    the Feb 10.26 - 15.89 arc. Using only the Feb 15 observations, with a low fixed
    rate of decay, I obtained nearly the same mean motion, so the main question is
    whether the acceleration will continue. Since the object's rotational
    acceleration has ceased, I suspect that its orbital acceleration is about over,
    in which case the object should be progressively a bit late relative the
    elements below.
