    Notes:
    -------
    
    (1) Possibly last observation of #90006 as it is now moving into daylight.
    
    (2) Did a search for XSS-11 - negative ( only found Noaa 15 )
    
    (3) Searched for the various new unknowns - no luck. Its obvious that the
        observed "discovery arc" is far too small making it almost impossible
        to produce a meaningful orbit. I have still to come up with a "simple"
        solution.
    
    
    Cheers
    Greg
