    --------------------------------------
    
    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 200mm focal length f/2.8 lens,integrating for 128 frames
    which is equivalent to a max exposure of 2.58 seconds per image.

    Notes:
    ----------
    *  = cloud
    ** = difficult
    
    (1)Power shedding on 7th April done 12 noon to 2pm so able to observe
       early evening !   Turns out South Africa has adequate power
       generating capability but approx 1/3 of power stations have no coal
       supplies so cannot operate!
    
       Power stations import coal at international prices but South Africa
       exports coal to Japan --- logic here escapes me.
    
       In addition we supply neighbouring states with power at far less
       than the domestic rate charged for power !!!!
    
    (2)Most of the RA/Dec measures above for shadow entry are observed,
       rather than using the predicted values from SPACETRACK elements.
       Even using the latest element set shows large errors in position,
       so whilst my positions probably not 100% accurate they are more
       realistic than the predicted coordinates.
    
       What puzzles me is the number of satellites shown by SPACETRACK in
       geostationary positions that do not exist!
    
    Cheers
    Greg
