    Notes:
    ------
    
    (1)  Last night of my exploring the possibility of using wide angle
         lenses to locate unknown satellites. Found 4 unknowns 91086,91087,
         91088 and 91089 but so far only 90186 has been "captured" and is
         now #90070.
    
         The remaining objects will probably remain lost unless found soon
         again by accident. All appear to be low inclination objects in
         eccentric orbits.
    
    (2)  Still have a few more to measure, mostly geostationaries - tried
         a new way to easily pick up geostationaries - looks promising -
         more later
    
    (3)  Now to measure 29 November which was "routine" tracking -
         something like 20 satellites despite much cloud - even got #90070
         in very strong twilight - enough light to drive a car without
         using headlights ( probably still get a "ticket" though because
         in South Africa the rule is " headlights on at sunset" although
         I dont think its strictly enforced as it depends on local
         surroundings - eg mountains etc.
    
    Cheers
    Greg
