    Notes:
    ------
    
    (1) An excellant session - maybe the end of my rainy season? I have
        still a LOT to report , hopefully tomorrow.
    
    (2) #91080 is a very interesting unknown as it was flying formation
        with #21798. I had a second pass and the unknown was still in the
        same position relative to #21798 so the orbits must be very similar.
        I have no match in my element database. The unknown was variable but
        easy for 90% of the pass. #21798 produced some very bright flashes.
        The second pass was difficult as the elevation was 11 degrees.
    
    
    (3) #91081 is probably a geostationary seen whilst following an "unknown"
        (which was subsequently identified). Except for a bright slow flash
        to +3 , which lasted about 4-5 seconds, nothing was visible. My
        database shows no possible candidate in the area.I had the area in
        question in my field of view for over a minute so the period is longer
        than a minute?
    
    (4) Still to report: (classified objects)
    
        #99906, XSS11 rocket, #90013, #90053, #25724 (Milstar 3),
        #90055, #90025, #24753 (DMSP 5D-2 S-14), #27168 (Milstar 5)
        #90034, #90046, #20344 (USA 40r),  #90063
    
        and several others which will need longer integrations to confirm
        or identify
    
    (5) Numerous strays ....
    
    Cheers
    Greg
