    Notes:
    -------
    
    (1) This bright suspected geostationary satellite was found on the 12th
        April whilst looking for #91023 ( which is lost for the moment).
    
    (2) Observations on the 14th April confirmed that it was a geostationary
        satellite. Observations indicate that it is variable in brightness
        with a variation less than 0.5 magnitudes - the observation giving
        a magnitude of +12.5 is suspect - I am surrounded by overhead electric
        cables and it is very probable that the satellite was then behind a
        cable which reduced the brightness ( the cables move slightly during
        the time exposures so I can see "behind" the cables ).
    
    Cheers
    Greg
