    Observations 02 May 2005:
    -------------------------------
    
    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 5 inch f/5 refractor, field of view 35.6 x 27.9 arc mins.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    90033 05 558A   0433 G 20050502182916100 56 15 0939024+070546 39  +112 05
    
    
    Notes:
    ------
    
    (1) #90013,#90016 and #27168 essentially steady magnitude.
    
    (2) #90034 showed slight variability - brightens as midnight approaches.
    
    (3) #90033 quite a long way "off" predictions, flashing every 2.5
        seconds and getting fainter. Took quite a lot of searching to locate.
        By midnight it starts to brighten again.
    
    (4) The 5 inch refractor is not suitable for general tracking as the
        field of view is too small making it too time consuming to find a
        satellite. This is aggravated by the relatively poor setting ability
        of the mounting due to backlash etc preventing better than about
        0.2 - 0.3 degrees setting accuracy.
    
    (5) Stopped by cloud - my cloudy/rainy season has arrived so I do not
        expect much observing the next 2-3 months.
    
    Cheers
    Greg
