    Notes:
    -------
    (1) A very frustrating session battling with clouds so missed most
        objects. Cleared when nothing more to track.
    
    (2) XSS-11 rocket - difficult for positional work as twilight still too
        bright and irregular brief flashes which seemed to take pleasure in
        flashing where no reference stars visible.
    
    (3) XSS-11 - quite an easy track, appearing quite bright in the south
        on ascending part of transit, then faded quite a lot when near
        culmination and brightened again just before disappearing behind
        local obstructions.
    
    (4) Alexis rocket bright most of pass, reaching perhaps mag +6 at max.
    
    (5) USA 179 Centaur rocket variable
    
    (6) Very short (~ 3-4 sec) track on Prospero just before shadow entry-
        a lot fainter than I expected. Track useless for anything other
        than one position.
    
    (7) Winter has come to Cape Town so tracking sessions will probably be
        far and few between - will give me time to work on my other
        tracking projects if Im not too lazy.
    
    
    Cheers
    Greg
