    Observations made 05 Sep 2002 #2
    -----------------------------------------
    
    CoSaTrak 1, 85mm f/1.6 lens with 0.003 lux CCD surveillance camera.
    Conditions - fair.  CCD camera now has remote focussing control.
    
    Herewith balance of observations and corrections:

    Corrections - obviously I have not yet fully awoken from my long slumber.
    The heading for my previous message should read "Observations for 5 Sept"
    and NOT 02 September.
    
    Both Ted and Paul pointed out a possible error in my position for USA 144
    (#25744). I checked the position and discovered I had reported the wrong
    star. Here follows the amended position for 20h17m04.4s UT and another
    position, this time hopefully with the correct stars-both were occultations.
    
    25744 99 028A   0433 F 20020905201704400 17 15 1908240-491838 39

    NOTES:
    
    (1) 75-043A was observed shortly after sunset - the sky was still quite
        bright with daylight.
    
    (2) The following unknowns were seen and identified:
    
        17:12:22 UT  Cosmos 724   75002A  mag 5.7 steady
        17:22:36 UT  Radarsat     95059A  mag 6.8 steady
        17:29:25 UT  Meteor 1-16  74011A  mag 6.4 steady
        17:48:49 UT  Meteor 1-12  72049A  mag 7.4 steady
        17:53:10 UT  Globalstar 5 98023A  mag 6.0 steady
        18:14:30 UT  Anna 1b rocket       mag 7.5 steady
        18:14:44 UT  Cosmos 2278 rkt      mag 3.5 steady
    
        These were observed as they crossed the approx 3x4 degree field of
        the ccd camera as it tracked another satellite so the satellites
        appearance is only as observed for a few seconds. I always make
        an effort to identify "unknowns" in case its something exciting.
    
    (3) I note the request on SeeSat for variability of Milstar 3 - when
        next I track/have a suitable pass I will pay particular attention
        to flashes/variability etc. Normally I do not worry too much about
        magnitudes of the objects I get positional observations for.
    
    (4) I also note that Ted asked that observers position be given when
        reporting observations- I shall try and remember to do this.
    
        Cospar Site #0433  Long 18.5129 E, Lat 33.9406 S, altitude 10 metres
        (GPS position - I live a few kilometres from the centre of Cape
        Town so have a "glorious!" city lit sky.
    
        Cheers
        Greg
