    Geosat flare season - southern hemisphere:
    ===========================================
    
    EXPRESS AM2   05010A #28629 18h20m14sUT  RA13h04m12s(J2000)Dec+05d09'15"
    THAICOM 5     06020B #29163 18h26m13sUT  RA13h04m04s       Dec+05d04'56"
    TELSTAR APS   97062A #25010 18h33m20sUT  RA13h02m47s       Dec+05d10'17"
    ABS 1         99053A #25924 18h40m07sUT  RA13h03m07s       Dec+05d11'14"

    Columns are:
    
    Common name - Cospar name - catalog number- time of shadow entry UT-
    RA and Dec position of satellite at time of shadow entry (from sat
    ephemeris) so could be a little out depending on how accurate the
    SPACETRACK elements are.
    
    
    Notes:
    ---------
    
    (0) Nil observations 04 April - cloudy
    
    (1) New unknown found - weather permitting I will make an effort to get
        more observations.
    
    (2) UFO F10 bright - little off track? - old elements?
    
    (3) TELSTAR APS faint so shadow entry time a little uncertain.
    
    (4) EUTELSAT W5 shadow entry - had cloud problems - so little uncertain.
    
    (5) Thereafter had to abandon observing as started to rain - I cant win!
    
    Cheers
    Greg
