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 .
