    Notes:
    -------
    
    (1) After about 5 days of almost continuous rain - my part of the country
        has suffered severe flood damage with roads and bridges washed away,
        but my area okay, it sort of cleared so conditions fair with a bright
        moon and a fair bit of cirrus. Everything was waterlogged from the
        high humidity when I shut down but none of the electronics blew up!
    
    (2) Dont know why I missed USA40 rkt previous time I tracked as easy but
        running a little early.
    
    (3) Took a long time to find 98029A ( was previously 90013 and the first
        geostationary I found) - maybe Im out of practice! Long way off predictions.
    
    (4) Again had trouble with the DVD recorder - paddle very intermittent when
        using the STEP/SLOW function which I need to step through the DVD
        recording.   After battling quite a while I eventually copied the DVD,
        satellite by sateliite, over to my computer hard drive using Mpeg2,
        after which I had to convert the Mpeg2 files to avi so it would run
        in VIRTUALDUB which did an excellant job of stepping through the
        recordings. There was no obvious loss in image quality. Next time I
        track I will copy the camera S-video output directly to the pc as
        well as DVD. Been meaning to do this for years but simply too lazy!
    
    Cheers
    Greg
