    NOTES:
    ----------
    (1) Partially cleared for a few hours after prolonged spell of cloud and
        rain -very cold ( for South Africa that is!)
    
    (2) Decided cant let those blokes in the northern hemisphere have all the
        fun so used the wide angle system, and despite being Friday the 13th
        it paid off.
    
    (3) Suspect I have recovered KH 9-18 #14139 last seen 12 June 2007.
        Irregular flashing  - seen by accident whilst waiting for SDS 3F4 and
        immediately said to myself thats a KH elint and sure enough KH 9-18
        was predicted to be pretty close despite the elset being so old-
        quite amazed but nothing else predicted in the area and everything
        fitted- eg track angle etc. Sheer luck .
    
    (4) Bright unknown geostationary found very low on eastern horizon. Since
        it doesnt match anything reasonably confident its related to the
        NROL-15 launch. Unable to secure further observations due to cloud.
    
    (5) KH9-17 running about 22 seconds late, XSS-11r about on time and
        Ofeq 9 also close to predicted time.
    
    (6) Had to stop when it started raining
    
    (7) Still have a lot of geostationary fields to process - will take a few
        days-- weather so cold at the moment my hands and feet are frozen!!
    
    Cheers
    Greg
