(meteorobs) Observation June 20./21.
Weather finally improved over here and I managed to get almost three hours of observing last night.
The nights are now painfully short at these latitudes (46 N). The activity was very good. In TEFF 2.64 hours I
saw 24 meteors. Most of them were sporadics, but there were also two SAG, one JBO and one possible
Xi Draconid. And as if the short night was not enough I was constantly surrounded by a swarm of B-52 mosquitoes.
I watched the area between head of Draco, Vega and Deneb. The limiting magnitude went down to +6.2 in
that area. The highligth of the night was a fast -1 magnitude sporadic, appearing in Cygnus and leaving a nice 2 second
train. There were also a 0 magnitude SAG and a 0 magnitude possible Xi Draconid.
But the most interesting part were not the bright meteors but a radiant which I did not find in any literature.
During the night I noticed very rapid, quite like Leonid, meteors coming from a radiant a little above Deneb.
I plotted five of these meteors which revealed a radiant at DEC +53° , R.A. 21h 30m. All of these meteors were between
+1 and +3 magnitude and very rapid. (this is probably a known radiant which I haven't found yet... ...so any suggestions
are welcome ). I labeled these meteors as SPO*.
During the last part of the observation, extending into dawn hours I kept an eye for Beta Taurids, but saw none.
