(meteorobs) AKM Video Observation December 2000
Results of the AKM Video Meteor Network - December 2000
=======================================================
December was a worthy final of a successful year of video observations.
There were long periods of bad weather at the middle and end of month, but
the large number of active observers and long winter nights compensated
for that. In the end, December was on the third place (after August and
September) with respect to the effective observing time, and ranked even
second (after August) with respect to the number of meteor records.
The highlight of December is usually the Geminid maximum - not so in 2000!
This shower was not only hampered by the moon, but fell literally into the
(rain) water. Of special interest, however, were the Ursids. Only weeks
before their maximum an outburst was predicted for the morning of December 22.
Fortunately enough, skies were clear over much of central Europe, resulting
in large numbers of visual and video observations that night.
By now the picture is still contradictory. There are observations showing no
enhanced activity, whereas others claim to see the outburst in their data.
Our video cameras also recorded largely increasing Ursid activity towards dawn
of the night in question.
Not included in this statistics are three observing session of Andre Knoefel.
Due to an error in the measurement of reference stars we had to remove
his 15.3h effective observing time and 44 meteors from the database. By now
the problem should be fixed.
