Results of the AKM Video Meteor Network - August 2000
=====================================================
August 2000 was a record breaking month: Never before we had that many
participants in our AKM video network, it's for the first time that one
observer alone managed to obtain observations in more than 20 nights, and
never before wed had such a good coverage with observations in 27 out of 31
nights. We had not at all a sensational good summer, but still there were a
few hours of clear skies in almost every night allowing us to collect at
least some data.
Our network further grew in the North-Rhine Westfalia area: Andre Knoefel is
operating his camera system from Duesseldorf, which allows regular
double-station observation with the AVIS camera in Aachen in the future.
During the meteor observing camp in Ketzuer the "light bucket" ESCIMO
was tested for the first time. This camera, which had been presented
already at the AKM spring meeting, records easily stars down to +11 mag
in a field of view of 5.5 deg. In this brightness range most meteors are
sporadic, and even slow shooting stars with <10 deg/s rush like a flash
through the fov. The limiting magnitude for faster meteors is therefore
significantly below the one for stars.
Detlefs camera got a new fast wide angle lens from FUJINON, resulting in a
larger field of view and many more meteor records. In one of the first test
nights the camera got almost lost in an flood-like rain shower at the Dutch
coast.
