    NOTES:
    -------
    (1) Quite an enjoyable session - no problems, pleasantly warm,
        some wind with good transparency.
    
    (2) USA 186 "recovered" - running a few minutes early.
    
    (3) MENTOR 2 #25336 moved again, this time westward.
    
    (4) Only one image of Geosat GFO #25157 - poor phase angle.
    
    (5) AMS 1 #09415 came out of shadow at low elevation heading
        downwards - end of trails not that well defined but should
        be okay.
    
    (6) A LOT more to come - going to take me 2-3 days to process.
        Started with 1608 files ( 8 Gbytes). After pruning out the
        "rubbish" ended with 1172 files. Still to process about 700
        files. I usually take 30 images per satellite pass and measure
        first and last files and one in the middle. The remaining
        images taken per satellite are checked for strays and
        identified/measured.
    
    Cheers
    Greg
