Hi everybody,

Here's a couple of obs in Moscow last evening April 22, with 8x30
binoculars.

USA 129 passed very near to Eta Vir (12h 19.9m, -00deg 40min, 2000.0)
at 18:07:15 UTC +/- 2 sec. It then passed E of Epsilon UMa (12h 54.0m,
+55deg 58min) at 18:08:20 +/- 1 sec. Both passes were 6 seconds early
against the elset:

USA 86 passed near Arcturus (14h 15.7m, +19deg 11min) at 18:31:14 UTC
while the prediction based on the folowing elset was 18:32:14. In theory,
I could err by 1 min but I believe my record was correct.

USA 86 was bright enough to be seen naked eye in Moscow light
pollution, especially low in the S at 18:30.

There were three predicted events in the NE at around 18:34 UTC making 
obs difficult. Apart from USA 86, Lacrosse 2 was to go NW->E (not seen,
but in strong pollution and unfavorable Sun angle) and -3m Iridium 7 flare 
(seen at 18:34:05, quite spectacular).
