    Observations 28 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 ~60mm focal length f/2.8 lens,integrating for 64 frames
    which is equivalent to an exposure of 1.28 seconds per image.
    
    Field of view approximately 5.35 x 4.25 degrees and showing stars down
    to about magnitude +09.5
    
    Site 0433 : Longitude 18.51294 deg East, Latitude  33.94058 deg S,
    Elevation 10 metres - situated in Pinelands (Cape Town), South Africa
    
    Correction for USA 186:
    ----------------------------
    Delete following line
    
    91041 05 298LEO 0433 G 20051028210637200 56 15 1341596-840414 39  +050 05
    
    and replace with this line:
    
    91041 05 298LEO 0433 G 20051028210637200 56 15 1310595-823614 39  +050 05
    
    The position given first time is incorrect and was position of
    centre of the field of view. The correction gives the position of the
    satellite.

    Faint about magnitude +9
    
    (b) Other known "strays:
    
    FREGAT RB/Cluster
    26106 00 015A   0433 G 20051028183013200 56 15 0207193+021035 39

    this followed the unknown #91042 and was slightly brighter - I
    suspect the two satellites are related as apparent angular speed
    and track angle were similar. #26106 was about a magnitude brighter.

    Notes:
    --------
    (1) This concludes observations for 28 October. I still have a few
        geostationaries to measure from 25 and 27 October.
    
    Cheers
