    Observations 25 Oct 2005:
    ----------------------------
    
    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 145mm focal length f/2.5 lens.
    
    Due to the operator not being "totally with it" it seems I had one of
    the settings on the MINTRON incorrect with the result that images were
    not integrating. The effect of this was to dramatically reduce the
    sensitivity of the camera.

    New launch object NRO-20?
    -------------------------------------
    
    Using Teds revised search elements dated 20 October, I did a search for
    the new object and the following was seen - I do not have any other object
    predicted in the area the time so it may well be the new launch. It was
    quite easy and appeared steady during the short time it was seen. It was
    running a few minutes early on the estimated elements which were about 5
    days old.

    96072A- #24680- USA 129 was NOT seen using elements 15 days old so has it
    been de-orbited?
    
    
    Notes:
    --------------
    
    (1) After an enforced absence due to surgery I am now "building up steam"
        again and hope to start tracking regularly soon.
    
    (2) The main purpose of the session was to try and locate NRO-20.
    
    (3) Still to report:
    
        MILSTAR 3 #25724
        DMSP B5D1-4 #11389
        NOSS 5(D) #14144
        KH9-19 #15071
        Lacrosse 2 #21147
        NOSS 3-2 Rk #28096
        DMSP B5D2-8 #23533
        Lacrosse 4 #26473
        DMSP B5D1-1 #09415
        ATEX #25615
        DMSP F-16 #28054
        USA 89r #22519
    
        plus about a dozen of the geostationary satellites visible over my
        area that appear in CLASSFD.TLE and hopefully not too far for the reduced
        camera sensitivity.
    
    (4) I plan to track tomorrow night - 27th October using a wide angle lens
        so I have a better chance of seeing NRO-20 etc.
    
    Cheers
    Greg
