[Mikhail Maslov]

My greetings.
An observation on July 23. Conditions were average for Novosibirsk
with lm=5.7. Activity was not bad, many bright meteors, perseids
amounts are gradually increasing.
I should specially mention several particularly impressive meteors.
17:30 UT - just after start of observation
- an excellent Perseid, which left the train for 4 seconds; 17:48 -
probably graser, very dim but long, during its flight it vanished and
appeared again;
18:19 - quite bright and very long meteor, was flying northwards for 5
seconds; and finally a couple of meteors at 18:34, appeared in the
interval of several seconds.
