We observed Gorizont 14 flashes at three different times on
Saturday night. Selected flash times:
Dec 29, 2002 UT
1:32:31.0
2:49:25.0
4:50:34.1
At the second time, secondary flashes were about magnitude 6.5.
At the third time, secondary flashes were about magnitude 9.5.
These occurred half-way between primary flashes.
Primary flashes were "slow" (in an 8 inch telescope) and about
magnitude 4.
Second - first = 4614.0 seconds / 53 cycles = 87.057 +/- 0.002 seconds
Third - second = 7269.1 seconds / 83.5 cycles = 87.055 +/- 0.001
Third - first = 11883.1 seconds / 136.5 cycles = 87.0556 +/- 0.0007
It seems there was a phase shift between the second and third times.
Friday night time: Dec 28 at 3:56:45.0
Third time - Friday time = 89629.1 seconds / 1029.5 cycles =
87.0608 +/- 0.0002 seconds.
It was cloudy Sunday night and will be cloudy tonight, but if
I can get a flash time tomorrow night, I should be able to
compute flash times for all times in between Dec. 28 and Jan 1.
Even an East Coast or West Coast observation might show a one
second difference from my flash times.
