    ------------------------------------
    
    Cosatrak 1 (Computerised satellite Tracking System).
    
    FLI ML8300M CCD camera with mechanical shutter + Trimble GPS
    
    Used with 135mm focal length f/2.8 TAMRON lens.
    Field of view 7.6 x 5.7 degrees.
    In ALL cases exposure was 2 seconds, one being taken roughly
    every second and under GPS time recording.
    
    Only Geosat images processed with APEX, rest manually
    Approximately 1300 images taken of which about 330 contained one
    or more satellites.

    NOTES:
    --------
    (1) The rest of observations made on 02 Oct 2013 and, except for one set
        of images of the area around the geostationary satellite, all other images 
    of the
        predicted path of FALCON 9 using an early set supplied by SPACETRACK.
    
    (2) First the geosat area - 5 images taken through thick cloud - barely
        nothing visible to the naked eye. I used APEX to process the images
        and it produced results for two of the images. I hope I have the
        identity of PAN correct using the prediction element set I used.The
        unknown identified as 00015 appeared as a short trail, at right
        angles to the star trails,in only one of the five images so is
        probably a spurious object as I cannot confirm it. I do see from
        GUIDE however that I was very close to the earths shadow for
        satellites at about the observed range at that  position so it
        could well have been an earth shadow problem restricting
        visibility.
    
    (3) The other unknown was discovered in one of the FALCON 9 zones
        watched. It is NOT a Falcon 9 object. I find no match, but as
        shown in my first report it would appear my SPACETRACK catalog
        was missing at least one major object so it might well be another
        missing object.
    
    (4) The unknown , reported under FALCON 9 as #88888 only appeared on
        one image and was so faint I am not 100% sure that it was not an
        artifact as no FALCON 9 object was near it at the time, so this
        to be treated as suspect. Difficult to measure.
    
    (5) The other FALCON 9 object is the rocket - my SPACETRACK elset
        showed it as being object B but Dr.T.S.Kelso's posting of
        elements yesterday indicate that the rocket is object G which
        is very close to B. The optical setup I used would not be able
        to see both objects due to the magnitude difference and
        possible proximity , so strictly speaking my idents reported
        as object B should now be corrected to object G.
    
    (6) The "seeing" reported by APEX for the images it processed showed
        that seeing conditions were almost unbelievably bad - 45 arc
        seconds! This is certainly not impossible for my location which
        normally averages around 12-15 arc seconds and a good night never
        being better than 8 arc seconds, so I believe the seeing
        reported, especially as it was the start of another cold front
        hitting Cape Town. The seeing would have been better in the
        short time preceeding the arrival of the front.
    
    (7) I hope I havent made any mistakes - the past week has been
        extremely hectic and Im still not out the woods as a pile of
        email to process....
    
    Cheers
    Greg
