    Observations 28 Mar 2006:
    ----------------------------
    
    Cosatrak 1 (Computerised satellite Tracking System).
    MINTRON low light level CCD surveillance camera (0.005 lux typical
    in non integration mode) and 0.00005 lux in STARLIGHT mode with 128
    frame integration.
    
    Used with 82mm focal length f/2.0 lens,integrating for 128 frames
    which is equivalent to an exposure of 2.56 seconds per image.
    However, due to incorrect setting of the MINTRON the exposures varied
    considerably.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    Notes:
    =======
    
    (1) A good night hampered by using a substandard lens which produced
        a soft focus, had quite severe coma on bright objects, and an image
        scale that varied across the field of view - note to self - bury
        this lens!!!
    
    (2) Main purpose was to observe #90020 and #90027 and the two new
        geostationaries found a week ago. The former objective was achieved
        but lens useless for the majority of geostationaries.
    
    (3) The position for #24753 or 97012A was difficult due to low elevation
        and poor images.
    
    (4) Nice track on #90027 running about 22 seconds late on my elements.
        Satellite got as bright as mag +3 and appeared to be showing a
        regular variation but difficult to see when the image is integrated-
        satellite appeared to be "pulsing" for about a minute otherwise
        appeared steady 90% of the pass.
    
    (5) #90020 flashed the entire pass observed.
    
    
    
    Cheers
