    NOTES:
    --------
    (1) Experimenting to see capability of equipment for finding random
        satellites -- can detect leos as faint as mag +8.5 and high altitude
        slow movers at about mag +10 or +11.
    
    (2) Unknown high altitude found. Suspect its real as this particular
        lens is not known to give internal reflections.  The orbit given
        assumes circular which it probably is not. Had slight variability
        of about half a magnitude but visible all the time.
    
    (3)All measuring done manually.
    
    Cheers
    Greg
