    Notes:
    ------
    
    (1) Remove unknown #91071 - it has been identified as Milstar 6 rocket,
        #27712 so amended entry above.
    
    (2) Not totally convinced about #27938. This was passing over near
        apogee and difficult. I did three integrations - one showed something-
        reported above, the second integration had a bright star obliterate
        anything near by and the third integration showed nothing , so ???
    
    (3) My tracking system is now out of operation for the next few days-
        I have to replace cabling and connectors - essential maintenance!
        Frustrating when the screen suddenly goes black because the 12v power
        to the CCD cable fails due to some intermittent connector. I will
        probably replace the current 12volt supply with a motor cycle
        battery near the camera - this will remove noise pickup on the cables
        etc.
    
    Cheers
    Greg
