(meteorobs) videoobservations 20100115-20100121

[Mikhail Maslov]

The main event of this observing - the probable confurmation of gamma
Ursa Minorids actiivity on January 20/21, this shower was indentfied
by Finnish observers. Four meteors with characteristics suitable for
this shower were detected during Teff=5.00h.
Among other events I'd like to underline aboundance of bright meteors
in the night 18/19 January, which gave three meteors of -2.5, -2.5 and
-3.5 mag (of 18).
On 19/20 January there were 2 remarkable meteors. One of them was a
slow fireball of -3.5 mag with a flash of -7 mag. And the second was
an excellent sporadic of -1 mag, perhaps it was a graser, as its track
lenth was 47°. A very impressive seeing.
On 20/21 January night the most remarkable were two simultaneus
meteors. Considering the absence of high activity that is a quite rare
event.
