    Notes:
    
    (1) Shuttle observed 19:30UT but no obvious signs of a water dump.
        Next possibility for my location is Jan 28,2003
    
    (2) Both USA 116 and USA 161 were not observed as they were at too
        low an elevation with houses etc in the way.
    
    (3) USA 144 (99028A) was observed in order to try and get some
        "photometric" results. The following were the approximate times
        of minima:
    
        22h39m24s,22h41m11s,22h43m04s,22h44m53s,22h46m45s,22h48m39s,
        22h50m26s,22h52m19s UT.
    
        The minima is very shallow and lasts perhaps 5-8 secs, and
        similarly the maximum is not well defined so its rather difficult
        to get an accurate period, however over the seven cycles observed
        the period comes to approximatly 111 seconds.
    
    (4) Satellite 92-023A was observed accidentally whilst waiting for
        another satellite so the two positions are when the satellite
        flashed as it crossed the field of view.
    
    Cheers
