(meteorobs) AKM Video Observation Results May 2001
Results of the AKM Video Meteor Network - May 2001
==================================================
After there was one negative record after the other in the previous months,
the observers were finally awarded with better weather in May. In Germany
we had stable high pressure systems both in the first and second part of the
month resulting in blue skies and summer-like tempatures. Thus, active
observers easily finished with more than 10 observing nights. Using also small
cloud gaps I even managed to have only one break in the whole second part of
May. What's missing is the night that we partly spend together with Rob
McNaught in a Pizzeria in Darmstadt. However, that night was overcasted,
anyway. :-)
Steven Evans of England now started with "real observations", even though
he could collect only a limited number of meteor records due to the short
nights. Ilkka Yrjola observed his last meteor before the summer break at his
high northern latitude, and our colleagues at the Canary islands observed
up to 40 meteors a night thanks to the longer night time. There were an
overall of more than 850 meteors recorded in Europe, which is far more than
what we recorded that month in the last two years together.
Rob McNaught spent most of the month in the US and Europe, but still managed
to collect more than 20 observing nights. How's that possible? His colleague
Steven Qirks operated the camera down under at that time! With the increasing
duration of southern night the number of meteor records from Australia is
still growing amazingly. Meanwhile this camera records more than the European
systems during the Perseid maximum, and the tendency is still upward. It has
to be noted, however, that the figures are still preliminary and might get
down a little after another inspection of the data. In addition, the effective
observing time of SSO1 contains also hours with overcasted skies.
In the first part of May there was probably a minor shower active, which did
not made it yet into the IMO meteor shower working list. The eta-Lyrids are
currently under closer investigation in cooperation with visual observers
from the DMS.
By the end of May we were looking for meteors from comet Schwassmann-
Wachmann 3, too. The video records revealed the same result as visual
observations: There were virtually no meteors from the predicted radiant.
Only Rob McNaught recorded about a dozen candidates. Given more than 300
meteors that night, however, these were probably by-chance alignments.
