hello all,
I was able to observe Gorizont 23 on Thursday and this Friday evening,
it was flashing with maxima of mag +5 to +6. I was able to make detailed
observations and can confirm that the period is indeed still going down.
Below you can see some recent observations (including my latest timings)
that will be part of the next PPAS update which I'm preparing right know and
will become available one of these weeks.
