    Observations 01 Feb 2005  Part 1
    ----------------------------------------
    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!

    Notes:
    -------
    (1) #23533 -95015A - images washed out due to bright city lights
        as a result of observing pass with maximum elevation 15 degrees.
        Sky really too bright for integration but satellite too faint
        for normal observation.
    (2) #22638 - 93026A - tracked on predictions and positions when
        satellite flashed were measured - stars did not always oblige
        by being suitable reference stars so one or two positions may
        be a little off.
    (3) #23031 - 94017B - another low elevation pass track -maximum
        elevation 15 degrees.
    (4) #05678 - 71110A - only tracked it below 14 degrees elevation
        as I almost missed the pass so only got the end of it.
    (5) #24680 - 96072A - thought this had finished trackable passes
        for me due to local buildings etc but managed to get these
        positions through gap in house roof - I think this may be the
        first time both northern and southern hemisphere have been
        able to observe this satellite on the same day ?
    (6) Still a few more to report - nothing exciting - Ive done enough
        measuring for today!
    
    Cheers
    Greg
