    Observations 20 Feb 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 135mm focal length f/2.5 lens,integrating for 128 fields
    which is equivalent to a max exposure of 2.56 seconds maximum
    per image, but dependent on sky brightness. Field of view
    2.4 x 1.8 degrees.
    Individual frames are video time stamped with GPS derived signal.
    Images processed and measured manually.
    
    (2)Meade DSI Pro II Monochrome CCD camera without filters.
    using integration times of 05 sec min to 30 seconds maximum
    depending on brightness of sky in particular area.No image
    processing done but dark field applied.
    Used with 102mm aperture f/2.56 refractor ,field of view 84 x 63
    arc minutes. Can get to magnitude 13 or so in less than 20 seconds
    exposure.
    Exposure time to nearest second inserted into image FITS header
    from PC clock which is checked against GPS signal.
    Images processed and automatically reduced using APEX.

    Notes:
    ===============
    (1) Conditions poor -- poor transparency and then bright moon.
    
    (2) Failed to see MERCURY 2  #23855. Has not been seen since mid
        2010 when it was moved.The latest COGO13 elements show it to
        be drifting so probably was being moved again and for the
        moment is lost. The INT elements are no good as its probably
        based on the time last observed by amateurs.

    Notes:
    ==============
    
    (1) The two unknowns seen are almost certainly related - similar time,
        track angle and appearance. A rough calculation gives an inclination
        around 25 degrees, RA Ascending Node about 195 degrees, revs/day
        about 12.5 revs. Standard magnitude about 7.7.
        The first object was flashing rapidly - regularly - about 5 times a
        second and the second object was similar but a bit fainter. Objects
        are probably debri and probably not cataloged since they dont pass
        through the NAVSPARSUR fence. Not worth bothering about.
    
    (2) OFEQ 5 brightness is very phase dependent. When rising in the east
        it is probably a naked eye object but as it reaches culmination as
        it heads west it fades very rapidly until eventually too faint to
        see ( fainter than mag ~ 8.5).
    
    Cheers
