    NOTES:
    -----------
    (1) Doing some experimenting. Moon too bright for the fainter geosats so
        did a few leo sats. Two unknowns seen for which I dont have a match.
        As I did not see them in "real time" I hope I have the direction
        correct - going the "other" way gives unusual inclinations.
    
    (2) Looked again for 90070 - nil seen - it was doing a near perigee pass
        so time error would make a big difference but did try using wide field
        of approx 15 x 11 degrees.
    
    (3) This time got USA 186 just as it cleared local roof before shadow entry.
    
    Cheers
    Greg
