    Observations 11 Jan 2011
    ----------------------------
    
    Cosatrak 1 (Computerised satellite Tracking System).
    Camera mount now carries two systems that can be operated
    together as two totally different sytems and computers used.
    Generally the DSI Pro II camera will be used for high altitude
    slow moving objects. Tests seem to indicate that its sensitivity
    is comparable to the MINTRON ( possibly better) but as its not
    possible (?) to time stamp to better than 1 second accuracy the
    time resolution is not good enough for LEO objects.
    
    (1) 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 145mm focal length f/2.5 lens,integrating for 128 fields
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image. Field of view 2.4 x 1.8 degrees.
    Individual frames are video time stamped with GPS derived signal.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa

    NOTES:
    ---------
    (1) For a change decided to do video only observations in order to test
        out a computer replacement with a faster PC which resulted in a
        smoother and faster tracking motion.
    
    (2) Still to report:
    
        90070
        DMSP F1 (#09415)
        USA 81
        USA 179
        NOSS 0-(C) (#05680) - maybe - might have been a stray
        NOSS 0-(E) (#05682)
        90083
        DMSP-F4 (#11389)
        NOSS 2-1 triplet - reasonably in formation still
    
        plus all the strays seen - hopefully tomorrow. My eyes have had
        enough for today.
    
    (3) Whilst tracking on DMSP-F4 I got the distinct impression that I could
        resolve the shape of this satellite - an elongated bar with a bright
        "knob" at each end, flying at an angle to the path trajectory, and
        had an offset "knob" on one side roughly in the middle of the elongated
        bar.
    
    Cheers
    Greg
