    Observations 31 Dec 2011
    ----------------------------
    
    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 82mm focal length f/2.8 lens,integrating for 128 fields
    Field of view 4.3 x 3.1 degrees.
    
    Wider angle system added. Meade DSI Pro II Monochrome CCD camera,
    with 50mm focal length f/1.8 lens, continuous 4 sec exposures.
    Field of view  7.1 x 5.2 degrees. Due to nature of camera position
    times are not more accurate than about 1 second, despite PC clock
    controlled by Trimble GPS setup. Observations made with this
    setup have code 18 in the report below.
    
    All images measured manually.
    
    Individual frames are video time stamped with GPS derived signal.

    NOTES:
    -------
    (1) Thanks to the efforts of Mike and Ted the bright unknown has now been
        identified as IGS 7 #37954 11-075A . The next task is to locate the
        corresponding rocket.
    
    (2) Transit 11 very variable, from +3 to invisible. Short,irregular
        period
    
    (3) ESSA 4 variable +6 to invisible
    
    (4) Surprised at how bright CHIPSAT is but everything matches.
    
    (5) My visibility window to USA 186 is now over but the orbit is good.
    
    (6) I have not yet processed the approx 2500 images secured with the
        wide angle CCD camera.
    
    Cheers
    Greg
