    NOTES:
    ------------
    (1) Unexpected clear evening in spell of really bad weather.
          At this moment wind howling, rain pouring and cold !!
    
    (2) Purpose was to check on status of USA 237 -- still drifting
        and to get a good track on 90087 which was the first unknown
        reported in my last observing spell of 7 August. Got a good
        track from quite a way out down to perigee.  Unknown was
        identified by Mike.
    
    (3) Another bright unknown about magnitude +8, medium altitude
        and steady - found whilst imaging Milstar 5 field.
    
    (4) Still more to measure - hopefully tomorrow.
    
    Cheers
    Greg
