    I checked the TLE's, but no MM-jump.
    
    This sat (13777) has a MM very close to 14 rev/days
    and it is oscillating around this 14th harmonic.
    The MM is slowly increasing from 13.9985 in dec 2002
    to 14.00027 in jan 2006.
    
    In PPAS this sat has been reported flashing from time to time.

    No chance to observe as it is still clouded for sevaral days
    and no improvement expected.
