    Observations 09 Mar 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.
    
    Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 05 sec.
    Used with 12.5mm focal length f/1.8 lens,field of view 26.5 x 21.4
    degrees. Stellar limit about magnitude +9 to +9 depending on
    elevation ( city sky brightness).
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is checked against GPS signal.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude -33.94058 deg,
    Elevation 10 metres-situated in Pinelands (Cape Town),South Africa
    
    POSSIBLE X37B - OTV-2

    Notes:
    ---------------
    (1) Possible observation of USA 226, using a wide angle system on the CCD
        camera. The video system used a narrower field of view and missed
        the object.
    (2) Hopefully will be able to confirm the orbit tomorrow morning - if I
        can stay awake - been running short of sleep the past few days!
    
    Cheers
    Greg
