    Notes:
    ~~~~~~
    (1) Due to a mains power failure in Cape Town today for 3 hours I was
        unable to measure - hopefully I shall report the remainder tomorrow.
    
    (2) Still to report the following satellites:
    
        Lacrosse 2, Noss 3-2 pair, #90025, #21798 (DMSP B5D2-6),
        #23533 (DMSP B5D2-8),Noss 5(A), #11389 (DMSP B5d1-4),
        #24753 (DMSP 5D-2 S-14),#28054 (DMSP F16), #25615 (STEX),
        #28385 (USA 179 Cn R)
    
    (3) Cosmos 304 (#04138) was measured by "mistake". Thought it might
        have been Noss 5(G) running early but turned out to be Cosmos 304.
    
    (4) Satellite #20299 (89084C) Galileo IUS was observed as an unknown
        as it crossed the path of Noss 5(A). Unfortunately turned out to be
        a known satellite and in an interesting orbit.
    
    (5) Another unknown observed MAY be #90004 running about 6 minutes
        early and last observed 108 days ago. Unfortunately I was busy
        tracking another satellite so got no positions other than a
        rough estimate. However next time I track I will make a special
        effort for this object.
    
    (6) With summer time now in the southern hemisphere is seems that the
        night sky is full of satellites and unpredicted satellites are being
        spotted all the time. In an effort to try and sort out the known
        from the unknowns the CoSaTrak tracking program, that controls my
        ccd cameras, will shortly be displaying on the monitor details of
        all known satellites that are predicted to be in my field of view
        of the 10 degree camera so that I can immediately decide whether to
        abandon the scheduled satellite or go off after a potential unknown
        so as to observe as long an arc as possible in the hopes of the track
        being good enough to derive an orbit that will enable me to find
        the satellite the next evening. My thanks to Willie Koorts who is
        constantly improving CoSaTrak as I ask for more and more features.
        New versions of CoSaTrak are coming out almost daily at the moment!
    
    (7) USA 32 is a "real pretty" satellite to observe - looks like the
        flashing light atop a police car -- now if it had a siren also ?
        Was flashing to about magnitude +3 for part of the transit before
        settling down to around magnitude +7
    
    Cheers
    Greg
