[Mikhail Maslov]

My greetings.
The observation in the night before Bootids outburst. The
conditions were very bad. The light night and considerable cirrus
clouds resulted in lm varying between 4.0-4.5 m.
During 2.43 hours of effective time I saw two bright meteors, both I
defined as Bootids. The first one appeared at the edge of my field of
view, quite far from radiant and was visible not very long time.
But the second one turned to be much more spectacular. It had distinct
red color, was flying south-eastwards during 3.5 seconds and leaving
the train, which quickly disappeared however. The rest part of
observation was free of meteors,
and at the morning twilight beginning I stopped.
I couldn't observe on 23 and 24 June because of total overcast.
