I had a prediction for a low altitude pass of the UHF Follow-On 8
Centaur rocket last night. I was surprised to see it tumbling
with a rather short period.
UFO 8 Cent Rk
1 25259U 98016B 99330.01322398 .00059078 00000-0 47043-2 0 5488

The fundamental period seemed to be 8.2 seconds, but there were usually
tumbles 1/2 way between these. There were also some sharp flashes.
It tumbled to about magnitude 5 at a range of about 1100 miles.
Gorizont 17 was observed flashing to about magnitude 4 about 0300UT
at alt 45, azi 205. The period was measured at 92.42 seconds.
This is about 0.5 seconds shorter than what I measured in September.
Secondary tumbles to magnitude 9 or 10 were seen 1/2 way between
the primary flashes.
Obs from lat 30.3, long 97.8 west.
