    Notes:
    --------
    (1) USA 81 #21949 difficult since observed in very bright twilight in
        the western sky. Only a few flashes seen and problems in seeing
        background stars for position determination.
    
        USA 102 #23031 was also seen but no reference stars seen - appeared
        to be on time.
    
    (2) USA 129 not moved yet.
    
    (3) USA 186 now back in visibility - will get higher in elevation for
        a while. Was a bit late on my predictions.
    
    (4) Lacrosse 5 rocket observed at 6.3 degrees elevation max.
    
    (5) Still to report - a lot of geostationaries plus strays seen as
        well as Vanguard 1 and Vanguard 3 observed - Vanguard 1 was faint
        whereas Vanguard 3 was a lot brighter. More with my report tomorrow.
    
    (6) A faint unknown was seen and using Scott Campbells ELFIND program
        I get the following orbit:
    
    1 91057U 06018M   06018.84958912 0.00000073  00000-0  50000-4 0    00
    2 91057  16.7060 119.4714 0005682 150.7036 180.0000  7.74099703    09
    
        Using Scott's SATID I did not find a match in my nearly 9000
        elements database so it looks like a real unknown,probably
        related to an Ariane launch. I dont propose to try and get it
        again as it is too faint and the observed arc too small to get
        a good orbit.( Ill try but not too hard :-))
    
    
    Cheers
    Greg
