    Notes:
    ==========
    
    (1) Main purpose was to observe 90-102G. Was running about 1m 14sec EARLY
        on prediction element set about 1 day old. Interesting satellite
    this!.
        On ascending part of 79 degree elevation pass appeared variable with
        a fairly regular period. After culmination it appeared basically
    steady.
        (difficult to say exactly what it was doing as each image integrated
    for
        1.28 seconds)
    
    (2) Unfortunately missed pass of #90027 due to 90-102G and Prospero so
    have
        still to find it.
    
    
    (3) No tracking tonight - lot of cirrus about and cold front expected to
        pass over Cape Town this weekend which usually means bad weather.
    
    Many thanks to all those who informed me that they were getting the SeeSat
    digest complete - looks like the problem is my end - either my server or
    maybe even my virus scanner - thinks Im a virus and deletes me ?? That
    will
    be quite a job as I am a pretty BIG virus !
    
    Cheers
    Greg
