 Hi all -
 I timed three high-flying (geo synch or thereabouts) satellites Sunday
evening local time, or Feb. 21 UT.  Here's the Highfly outputs, followed by my
observations, all made with a 32-cm reflector at 100x:

 23794 = Raduga 33 = 96-10A
 03:16-03:50 UTC, mag. 12, fl. mag. 5; fl. mag. 9 at 1/4 and 3/4 cycle.  Timed
120 cycles in 2040.5 sec., period = 17.004 +/-0.004 sec.
 
 20771 = BS-3A Yuri 3A = 90-77A
 04:01-04:17 UTC, mag. 11-13, fl. mag. 9; fl. mag. 5 two hours earlier, 02:08-
02:15 UTC.  Timed 12 cycles in 1046 sec., period = 87.17 +/-0.08 sec.
 
 17969 = Gorizont 14 = 87-40A
 05:04-05:41 UTC, mag. 12-14, fl. mag. 5 (visible at 1x); around mag. 11 at
mid-cycle.  Timed 26 cycles in 2204 sec., period = 84.77 +/-0.04 sec.  This is
embarrasingly consistent with Rob Matson's report on his timing report from 2
days earlier.
 
 Kurt - I've already sent these observations in PPAS format.
