    NOTES:
    --------
    (1) Plan was to mainly track LEO objects but at start of session
        computer refused to communicate with the mount so computer
        replaced but this had an older version of the COSATRAK
        program  so could not use the LEO predictions to track on
        so decided to only do high altitude satellites as setup then
        being used in GOTO mode.
    
    (2) No sign of USA 237 so it looks like it may have done a major
        change since last observed about 10 days ago. Searched a
        long way west of predicted position but appears not enough.
        Did a smaller search east of predicted position but could not
        go far on account of geosats being in earths shadow or close
        to it. Searched as far west as longitude 341 degrees approx
        (19 degrees east). Maybe its more west than that ?
    
    (3) This report is about half of what observed - hopefully rest
        tomorrow. I dont like this particular setup for geosats as too
        many objects in the field of view of no interest but all have
        to be identified.
    
    (4) Have still to determine cause of failure - looks like the LPT
        port has failed so will replace the pc - have several spare but
        installing a new computer means having to recalibrate everything
        since speed of operation etc depends on speed of the CPU. Easy
        enough to do but time consuming as one has to "sweet-tune"
        everything.
    
    Cheers
    Greg
