    Notes:
    -------
    
    (1) Purpose was to locate #90027. Thanks to input from radio observers
        was able to find the satellite.
    
    (2) Terrible night with MUCH cirrus ahead of approaching cold front.
    
    (3) Played with a new program Ive just found and its almost the perfect
        answer for my video tracking. Ive written to the author suggesting
        some "improvements".
    
        Its better than STARRY NIGHT and just as pretty, and FREE.
        The author obviously knows the needs of a visual tracker.
    
        Give it a try - download from
    
        http://www.heavensat.ru/english/
    
        It makes predictions using SGP4 or SDP4 and can handle up to 10000
        satellites. The star database supplied goes to about magnitude +9.
    
        Im now going to go and play with it some more.
    
    Cheers
    Greg
