    Observations 22 July 2003: (First half of observations)
    ------------------------------
    
    Cosatrak 1 (Computerised satellite Tracking System), 1004x low
    light level CCD surveillance camera (0.003 lux) with 145mm focal
    length f/2.5 lens with focal length reducer, field of view
    1.89 x 1.43 degrees, and a second camera has now been added,
    fitted with a 50mm f/1.8 lens as a "finder" which also uses a 1004x
    CCD chip. In this way I managed to track several satellites that
    I would have missed as they did not pass through the main cameras
    field of view which is rather small.
    
    Conditions excellant ( for Cape Town that is!!!)

    Notes:
    
    (1)    I no longer have an assistant typist to sit on my lap and nudge
        my hand from time to time,causing me to mistype.  Blackie my cat
        lost his battle with AIDS on Sunday 20th July when I had to have
        him put down as he was starting to suffer - from now on all mistakes
        are mine alone. Enjoy your freedom Blackie -you are missed.
    
    (2) Conditions were excellant ( that is for the Cape Town city lit skies).
        Maybe Blackie is on a higher plane now and keeping the smog away,
        polishing the satellites so that they are brighter, maybe even causing
        them to flash in the right place and also ensuring that they pass
    through
        my field of view. If you thought I was daft, now you know for sure!
    
    (3) Satellite 95015A # 23533 flared to magnitude -3 for several seconds on
        two occassions as it headed towards overhead - real spectacular on the
        video.
    
    (4) The remaining satellites will hopefully be reported tomorrow.
    
    Cheers
    Greg
