Hello.

An observation on 5 May. The sky was good, but the light summer night
allowed lm to reach only 5.1 mag. in the 1st hour of observations and
5.3 mag in the 2nd.
Activity, however, was definitely higher than in previous spring
months. During Teff=1.92 h I saw 10 meteors, three of them had
negative magnitude.
>From these three the first was a usual short meteor, only quite
bright. But I have never seen before meteors like the second bright
one.
It was about -1.5 mag, had red color, but the main thing is its
duration. It was flying for 7 seconds! During this time it passed
about 50 degrees from the zenith to the north-western skyline. The
third bright meteor was also not bad, it had medium velocity and -1.5
mag. During 2
seconds of its flight it passed a good distanse. Also I want to note
that all these bright meteors moved from south to the northern
direction.
