    Observations 04 Mar 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. Due to bright sky it is not worthwhile integrating
    more than 48 frames which is equivalent to an exposure of 0.96 seconds.
    
    Used with 145mm focal length f/2.5 lens giving a field of view of
    about 2.55 x 1.86 degrees and easily showing 12th magnitude stars.
    Not the best lens optically but the most useful in terms of field
    of view and magnitude penetration.
    
    Data recorded on DVD R/W disks - will be kept for 1 month and then
    re-used - just in case any queries as Im always making mistakes!
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa

    Notes:
    ------
    (1) 90017. I think I have finally found it after looking for it
        several times. I actually could see it on the monitor in real time
        flashing with a period of between 2 and 3 seconds ( closer to 3
        seconds). Not all flashes were of equal brightness but once spotted
        it was easy to see. It looks like the best time for me to look for
        it is in the early evening as it does not appear to be flashing/visible
        later ?
    
    (2) In view of the vagueness re the restrictions related to the possible
        use of SPACE TRACK data I will no longer report observations or
        positions for objects contained in their catalogs. Hopefully one day
        sanity will return. I personally think that ill-informed politicians
        (and even informed!) are a FAR greater threat to mankind than anything
        we could EVER do, even if we had the worst intentions.
    
    Cheers
    Greg
