    Notes:
    ---------
    
    (1) #90029 nice flasher, flashing at about magnitude +7 and invisible
        in between flashes. Period 64.3 seconds.
    
    (2) Vanguard satellites and associated rockets added to my prediction
        element set out of curiosity. So far Vanguard 1 and 3 tracked.
        Since these satellites are faint I track on predictions so if the
        element set is reasonably accurate the satellite will appear as a
        "stationary" object close to centre of the field of view as the
        mount follows the satellite. Stars are "trailed". This happened
        with both Vanguard satellites. Vanguard 1 was seen briefly from
        time to time as a variable object with maximum magnitude of around
        +12 , being invisible most of the time. Vanguard 3 was much easier
        and was seen most of the time and brightening to about mag 9.5
        at times , the remainder of the time being about a magnitude
        fainter.
    
    Cheers
