General remarks:
Observation terminated after one hour and no QUA observed, with high
moonlight disturbance. Field of view centered around beta UMi. Beautiful DCA
fireball of -8 mg observed at 00:50 UT going from delta Per to gama And,
paralelly with Cas. Another beautiful -3.5 mg COM observed at 01:33 UT.

General remarks:
Fine weather conditions with some high altitude clouds, especially around
21.00 UT. High humidity and light pollution from north. Until 23:40 UT field
of view centered around alpha UMi (Nort Star), after 23:40 around beta UMi.
Moon appeared around 21:10 and decreased limiting magnitude for almost 0.8
until end of observation. Light pollution from north dispersed moonlight and
caused Lm decrease. Field of view was centered as closer to the low radiant
as possible which also caused lower Lm (denser atmosphere, high altitude
clouds, light pollution from north). Lm varied rapidly across the sky - in
Per Lm was almost 0.6 lower than in UMa.
Please note that until around 23:00 radiant lays very low (around 10 degrees
above
horizon) in the region of high light pollution.
One bright -4 mg COM observed at 00:34 UT, and -3 stationary QUA at 00:08
UT. Lower QUA activity than expected, but with many beautiful earthgrazers
between 17:00 and 21:00 UT. Due to the physical exhaustion observation
terminated around 2.00 local time. Relatively low number of bright meteors.
