    Site 2701: 43.68764 N, 79.39243 W, 230 m
    
    Adding my observations of 03054A tonight to Russell Eberst's of last night,
    yields this preliminary post-manoeuvre orbit:
    
    Observation arc 2003 Dec 24.72 - 25.99 UTC:

    WRMS residuals = 0.055 deg
    
    Additional observation are required to refine the mean motion, but clearly it is
    now close to the expected final value of about 13.4044 rev/d.
    
    As expected, 03054C's matching manoeuvre is being delayed to allow it catch up
    to 03054A. Prior to 03054A's manoeuvre, 03054C trailed by more than one minute;
    reduced by tonight to 47 s. 
    
    When it has closed to within about 8 s, it will perform its matching manoeuvre.
    At the rate of closure indicated by the present elements, that would occur early
    on Dec 31, +/- a couple of days.
