(meteorobs) AKM Video Observation Results April 2001
Results of the AKM Video Meteor Network - April 2001
====================================================
Looking back at the weather in April, there is not much positive to report
on. In Germany it was the third month in a row with unusually poor weather.
At many places we had frequent snow falls until mid-April! It was only thanks
to a few clear nights at the end of April that the negative records of
February and March were not beaten. What's interesting is that the conditions
differed quite siginificantly from site to site. Whereas I, for example, had
hardly any completely clear night and accumulated only 25 hours of effective
observing time in 8 nights, there was Joerg who managed to observe as much
as 65 hours in 12 nights only 200 km to the north-west.
By the way, the moment when we will rename our network is approaching. In
this months we could welcome two new observers in our midst. Orlando Benitez
Sanchez has been observing from the Canary islands since fall last year, and
Steven Evans from Great Britain, who took part in a number of successful
Leonid campaigns, has also joined our effort.
Ilkka Yrjola, on the other hand, will have to take a break in the next few
months as the night sky is not getting dark anymore at his northern
observing site in Finland.
It seems we will get used to new records presented to us by Rob McNaught in
Australia. Even though he experienced a hard disc crash last month, which
resulted in a loss of two observing nights, he managed to record more than
3000 meteors in April. Everyone of us could become envy about these
figures. :-)
In the end the summary of April was quite encouraging thanks to the large
number of cameras. Never before we had 10 stations in regular operation.
In all nights but one there were at least one camera system active, and the
455 hours of effective observing time are a great result. Even if we take
out the observations from Rob for a moment, we captured more meteors than
last April, which saw much better weather.
