First : Next week I will create the next PPAS update AND the report
of 1997, so if you still have some observations of flashers,
made in 97 please send them...

This accelerating Gorizont will be visible over Europe for another
week or so, then our American friends have to take over...
I haven't been able to observe it during the last days because of
the weather, hopefully some other guys have beter conditions and can
make accurate measurements.
Also Gorizont 14 = 17969 = 87- 40 A is visible over Europe.
This is another older Gorizont that was detected flashing by
Daniel Karcher some weeks ago with his CCD. He found a flashing
period of about 120 seconds.
It would be interesting to know if this (and other) Gorizonts
are also flashing and accelerating ! :
Till now we have found that 4 Gorizonts have been seen flashing :
17083 g 86-090A GORIZONT 13 3.0 f95, 56s,m12,JHR?,D27D
will be visible over Europe next week
17969 g 87-040A GORIZONT 14 7.2 f98, DK, 120s D37D
19765 g 89-004A GORIZONT 17 f98, 84s D82D
21533 g 91 46A Gorizont 23 5.0 f98KJ,50s,m5.5 D72D
[from Mike McCants' highfly.mag, PPAS observations added in comments :
f95, 56s means flashing in 95 with a period of 56 seconds ; D27D means that
it takes the payload 27 days to drift around the earth]
