I would have IDed your sat as Gorizont 24 except that, as you indicated,
the declination was a bad match.

My report may not have made it into the database yet. I discovered it
on March 25 while timing nearby Gorizont 23 flashes. Flash period
then was 89.846 +/- .011 seconds. Here is an excerpt from my
Seesat post on 3/25:
"The exciting news from last night was that I discovered
another bright GEO flasher! At least, I haven't seen it
mentioned here. Not surprisingly, it's another Gorizont,

Brightest flashes were about magnitude +4. It's flash
period is 89.846 +/- .011 seconds. PPAS report:

This satellite is currently about 5 degrees east (in the
sky) of Gorizont 23. Its flashes should be visible from
most of the United States, though it is already getting
low in the southwest for observers on the east coast."
