Hi all. Here's February 28 - March 1 geosats. usually observed only enter to the shadow.
Brightness at shadow exit is after "exit:". All time is UT+2 (should be UT next time).
Coordinates are 48.5266 N; 35.018 E.
Obs done in 15x70 binoculars. Brightness measured by comparison with near similar stars.
I hope that the table using tabs, how it looks for me when I'm typing it, won't break for you.

Eutelsat 7A or B	28187/39163 	01:24 5.7;

There were two periodically flashing satellites:
Ekran 11 (1983-100A) - flashes 5 to 8 mag., 6 periods gave me 14.43 sec;
BSat-2c (2003-028A) - flashes 3 to 8 mag., period is about 7 sec (without stopwatch).
..and also 3 satellites which I spotted before I began measuring flare brightness with time:
Sesat 2 (Express AM-22) (2003-060A) and Cosmos 2513 (2015-075A) = about 5.5 mag;
Thaicom 6 (2014-002A) = about 4.5 mag.

60 sats in total.

Cheers,
Vlad
