    NOTES:
    =========
    (1) Excellant morning. Parked camera on az 019.8, elevation 39.7 degrees
        for about 80 minutes, looking for that elusive spaceplane.
    
    (2) During that period saw 2 classified satellites, 16 unclassified sats,
        3 meteors and 12 UFO's(birds) in 3 groups.
    
    Cheers
    Greg
