    Observations 19 June 2006:
    ---------------------------------
    
    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 100mm focal length f/2.5 lens,integrating for 128 frames
    which is equivalent to an exposure of 2.56 seconds per image.
    
    Conditions good - extremely high humidity which I dont like
    working with as it could damage the CCD camera.
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    Notes:
    --------
    
    (1) KH9-17 #13172 observed very strong twilight - satellite quite easy
        as it flashed periodically but very few reference stars seen-took
        the only one I could find close to the track-suspect its the correct
        star but if anything looks odd then ignore this observation.
    
    (2) Something I havent noticed before - DMSP B5D2-6 is doing regular +3
        flashes seperated by quite a few seconds.Can determine the period if
        anyone really interested :-))
    
    (3) Noss 2-2(E) is now about 37 seconds ahead of Noss 2-2(C) and
        Noss 2-2(D) - the last two still close together. Is Noss 2-2(E)
        still operational?
    
    (4) I had 4 Noss satellites in the field of view ( 3 degrees) at one
        time namely Noss 2-2(C),Noss 2-2(D) and Noss 3-3(A) and Noss 3-3(C)
        all flying parallel to one another, the maximum seperation in
        elevation being about 23 arc minutes. Quite noticeable how much
        brighter the Noss 3-3 objects were - about 2 magnitudes at least.
    
    (5) Think Ive found #90028 again, running almost 6 minutes late on
        SDP4 predictions ( Mike will no doubt tell me its less - I just
        report what GUIDE says :-)).   Measured quite a few points as
        PRC15 rocket at 11700 kms range was in the area at the time.
        However I suspect I have the identification of #90028 correct as
        it was increasing elevation when first seen, whereas PRC15 rocket
        was decreasing elevation. I did not see PRC15.
    
    (6) A few strays still to report as well as a few geostationaries which
        I hope to do tomorrow.
    
    (7) Now going to track a few satellites by radio...
    
    Cheers
    Greg
