Gorizont 23 is flashing nicely right now, at least for
the western U.S. (and probably the central U.S. as well).
Timed it for over an hour last night.  Flash period was
50.241 +/- .002 seconds.  In PPAS format:

91- 46A 99-03-24 04:38:41.9  RM 4571.96 0.15 91 50.241  mag +4 --> inv

The flashes were brightest at the beginning (mag 4), and much
dimmer by the end (mag 7).  I acquired it at 3:22:30 UT
(19:22:30 PST), but it was probably flashing as much as an
hour earlier.  So for those east of me, I'd start looking
as soon as it's dark.  Gorizont 23 was close to culmination
for me last night, so it is already dropping into the south-
west for our Seesat observers in Colorado, Arizona, New Mexico
and Texas.

Kurt Jonckheere timed this satellite's period at 50.308 on
99-03-03, so the period is still going down.

Coincidentally, Gorizont 17 was almost exactly above Gorizont 23,
in the same binocular field of view.  I looked for it periodically,
but never saw any flashes from it.
