Hello Leo,

I've just found out that there were standard filters
turned on in my Heavensat. I've reinstalled it recently
and have completely forget to turn them off. I'm sorry
for taking your time so foolishly.
Now it seems like it was one of two Globalstars which
passed here. Just got to identify which one exactly.
By the way, how did you do that points? Is it done with
ObsReduce? If so I'll try to understand how it works and
maybe will send positional data in this format to SeeSat
in future.

Sincerely,
Vlad.

> Today when I was staring at night sky between passes of interesting sats,
I've seen interestingly flashing satellite, but I couldn't identify what
exactly it was so now I need help to identify it.
My coords are 48,5266°N, 35,0180°E. All times below are in UT.
It was July 15, 20:17 when I've seen the first flash. It was in point of sky
with azimuth of 300° and height about 30°. The next flash was after 20:18
a couple degrees below 85 UMa. I've caught the sat in my binoculars, it
passed to the north from triangle of stars 21 Boo, 23 Boo, SAO 29046, very
close to them. And it flashed again. I've counted seconds before next flash,
which happened after 20:21 in Draco. I couldn't recall the right position of
the satellite in Draco, so it's trajectory in there might be wrong. Period
was about 40 seconds.
I've drawn the trajectory. You can see it here:

Flashes were consistent in brightness, of about -2 mag. Every flash lasted about half of
a second. When not flashing, satellite was changing brightness from 5 to 3.5 magnitude.
I've checked Heavensat with today's databases but couldn't find anything nearly fitting.
Any ideas?

Sincerely,
Vlad
