    Observations 14 May 2007:
    --------------------------------
    
    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 50mm focal length f/1.8 lens,integrating for 128 frames
    which is equivalent to a max exposure of 2.52 seconds per image under
    dark conditions.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    Notes:
    ---------
    Another almost solid cloudy night - did not expect to get any positions
    but after tracking blind on Teds last element set and going through DVD
    later and using a new technique for integrating images - even through
    thinnish cloud - was able to get the above positions and Im 100% happy 
    with
    them.  Magnitudes are not to be taken seriously as impossible to give an
    estimate due to the cloud but probably are fainter than in real life. 
    Range of
    satellite at last position was around approximately 10000 kilometres.
    
    This is my last observation of this object this "season" as the pass is
    now in daylight so its now up to other observers to track it. Teds and
    Scotts last elements are pretty good so it should not be a problem
    tracking it.
    
    Cheers
    
    Greg ( and Art Arnold - a friend of mine who returns back to London
    today - old tracking colleague of 42 years ago!- who also introduced
    me to my wife . )
