Results of the IMO Video Meteor Network - August 2007
=====================================================

Wouldn't it be time for a new record after the long dry period? But which 
ingredients are required to obtain more meteors that at any time before?

- Many observers: One reason for the ongoing success of the IMO network is 
the steadily increasing number of observers. There is always some fluctuation, 
but in general the network is growing. In August 2007, 22 cameras were 
operated by 16 observers. We could even welcome two new observers: On the one 
hand there is Stefano Crivello (as you may guess from his name, Stefano is 
based in Italy), whose camera had first light last month. This would have been
the first time with more Italian than German observers unless Niko Wuensche
did some testing with the new meteor camera of Archenhold Observatory in 
Berlin. In these days, the camera will be finally installed at the observatory, 
and in the future it shall give the visitors a better insight into meteors and
provide data to our network. By the way, at least with respect to the number 
of video camera the Germans still have the clear lead. ;-)
Summary: This ingredient to a new record was not missing in August.

- Active meteor showers: In principle you may expect new records only in 
August, October and December. Nobody will question August (Perdeids) and 
December (Geminids), but you may ask why October and not November (Leonids) 
or January (Quadrantids). The answer is simple - it's not only the meteor rate 
that counts, but also the length of the nights. The Perseids provide plenty of 
meteors for many nights, but the nights are quite short. October, on the other
hand, presents almost half of the Perseid activity thanks to the Orionids,
Taurids and sporadic activity, and the nights are almost twice as long. The
time of the Leonids is over, and the activity interval of the Quadrantids is
ways too short.
Summary: Also this ingredient for a new record was present, not to forget that
the Perseid maximum coincided with new moon in 2007.

- Good weather: In the end, everything depends on the weather. The most 
splendid meteor shower is worth nothing if you only record "hydro meteors".
In this respect, the last month was not perfect, but ok. Many observers 
collected more than 20 nights again, even if only few of these were perfectly 
clear. Just in time the weather cooperated with the observers: On August 12/13,
19 cameras were in operation (one of my automatic cameras failed just that 
night because of a power outage), and in the next night once more 15 cameras 
(here one of my camera failed because of a software bug - Murphys law!).
Summary: Also the most important ingredient was present by August.

So all things came together for a new highscore, and already by mid-August
the meteor number grew over 10,000. By the end of the months we had collected
nearly 14,000 meteors, which falls only slightly short of the so far best 
results (14,173 meteors in October 2006). However, 6 nights from REMO1 as well
as the data of KAYAK1 and ICC3 are still missing, so I'm optimistic that in the
end we may have even recorded close to 15,000 meteors!

With more than 1,500 hours of effective observing time, August presented a
respectable result, but in this category it cannot beat the autumn and winter
months (2,225 hours in October 2006).

Winner of the "beauty contest" last month were the Perseid plots from Biondani
Roberto and Bob Lunsford. Both aimed their cameras almost 
directly at the radiant. Bobs camera had a smaller field of view, which is why
his meteors were recorded closer to the radiant than Biondanis. 





However, not just the Perseids had drawn an interesting picture: Ilkka Yrjola
noted that the kappa-Cynids were remarkably active even at the end of their
nominal activity period (August 25). So I artificially increased the activity
period and recomputed the meteor shower assignment for all cameras. The result 
is shown below:



This year, the kappa-Cygnids were indeed active well beyond August 25.
Unfortunately, data is scarse at the end of August, but it seems they could 
easily keep up with the alpha-Aurigids at that time.

Last but not least I would like to point out, that detailed information about 
the IMO Video Meteor Network and the Video Meteor Database including the
monthly reports can now be obtained at http://www.imonet.org.
