    Subject:  "Red Dot" Observations in the Southern Hemisphere
    This is part of the Southern hemisphere geostationary flare
    program of Jeff Umbarger. His assistance and advice has
    been invaluable as well as the contributions from Bjorn Gimle
    and Rod Austin. I propose to observe every night until the
    "flare" season has passed.
    Equipment: CoSaTrak 1 200mm f/3.5.8 lens with MINTRON
    surveillance camera integrating for 128 frames (=2.56s
    exposure). Mount tracking on shadow entry point ( approx
    RA12h50m Dec +05deg. Field of view of camera 1.76 x 1.39
    degrees, star limit magnitude approx +12.5 mag.

    Rather thick cirrus which made timings of some satellites
    impossible. Eventually clouded out completely. I think the
    ones reported above are okay.
    Do not expect to be able to observe 10th April due to cloud
    and rain is predicted for tomorrow evening so things not
    too hopeful at the moment.
