[Mikhail Maslov]

Hello,
A Lyrid observation. The weather was unfavorable as a whole, three
nights 21/22, 22/23 and 23/24 were cloudy or
mostly cloudy. Only in the maximum night I was awaikened by an
alarm-clock and noticed that the stars are visible.
It was a break in the cyclonic cloud system. It allowed me to observe
during Teff=0.75 hour, lm was not good,
only about 5.6 mag. I saw 6 meteors, 5 of them were Lyrids of medium
and low brightness. It is remarkable that 4 Lyrid
meteors appeared in 5 min interval from 18:58 to 19:03 UT. At 19:35
clouds moved in again.
The next clearing came only today, so I'll try to do another
observation this night.
