    Notes:
    
    (1) Still a few more satellites to come but nothing exciting.
    
    (2) USA 136 rocket NOT seen - should have been as predicted bright and
        elements not old - will do a plane search for it next week. USA 125
        rocket not seen either.
    
    (3) Observed Raduga 27 behaving as follows - more detailed report to
        followed when Ive determined the time of flashes etc. I only looked
        at it when I had nothing else to observe so it was not continuous
        monitoring.
        (a) Observed 19:48 UT to 19:50 UT - nothing seen.
        (b) Observed 21:54 UT to 21:59 UT - triple flashes every minute or
            so ( will determine period), going to about magnitude +7.5 and
            invisible in between.
        (c) Observed 22:31 UT to 23:15 UT - now single flashes to about +7.5
            and period just over a minute.
    
    (4) Whilst observing Raduga 27 during the last session I found another
        geostationary flashing in the field of view. The flashes were about
        magnitude 7.0 and each lasted about 0.2 seconds and period was about
        42 seconds (will determine it more accurately from the video tomorrow).
        The satellite was identified as 94080A, Cat No #23415 and is DFH-3 1
        launched by the PRC (Peoples Republic of China). I suspect I may have
        seen several other "flashers" during the session but it is very easy
        to confuse a single flash with cosmic ray events which cause a short
        stellar like flash on the monitor screen- only by watching an area
        where a flash was seen is it possible to determine if not a satellite
        but the question is how long do you wait .
    
    Cheers
