    NOTES:
    -----------
    (1) Entire session marred by fast moving cloud which meant I could
        only do very short exposures- in many cases tracked "blind" on
        predictions with a rare glimse of the satellite with a few
        stars from time to time so unable to use APEX. In some cases
        the satellite (or stars) was not seen.
    
    (2) FIA RADAR 2 running about 1 minute late.
    
    (3) May have idents of the NOSS 3-4 duo incorrect - configuration
        does not match predictions so assumed identities on which was
        the most westerly object in the predictions.
    
    (4) Had a major scare when the CCD camera failed -panic stations
        but eventually found that the USB plug wasnt securely seated.
        In the process of trying to isolate the problem was unable to
        find my multimeter and the conclusion at the moment is that
        my "garden engineer" has "borrowed it on a permanent basis"
        and may explain why he has disappeared along with several other
        items I have been unable to locate. As a result of this scare
        lost about half an hour as I had to wait for the GPS system to
        re-acquire lock which took about 15 minutes- the CCD camera
        will not operate until lock acquired and seems to be a problem
        related to the particular GPS (Trimble) module used as my
        MOTOROLA GPS usually acquires "lock" in under 5 minutes. I
        did not enjoy this session....
    
    Cheers
