10 Years of IMO Video Meteor Network - Analysis Results


For the 10th anniversary of the IMO network, the comprehensive analysis of the IMO Video Meteore Database to date has been carried out. It was based on 451,282 single-station meteors collected by more than 30 observers in 3,363 nights and 107,594 hours of effective observing time between January 1993 and June 2009. The analysis was presented in WGN 37:4 (August 2009).

The basis was an automated meteor search as presented in 2006 and 2008. Thereafter, the individual showers were manually refined. For each of the more than 50 detected showers from the MDC working list, we presented detailed parameter (activity interval, maximum, radiant position and drift, velocity) as well as activity graphs. Two major findings were the detection of a constant drift of the velocity of certain long-lasting showers, and the detection of 12 so far unknown minor showers.

Some key results were presented in two talks of Sirko Molau and Jürgen Rendtel at the 2009 IMC in Porec/Croatia.

As always, we present a list of the individual radiants detected at each solar longitude. For each radiant, the following information is given:

Beware that only the strongest radiants on top of the list will be real, whereas all weaker ones are only by chance alignments of meteors.

Update: A new list of radiants per solar longitude interval was calculated from over a million meteors in 2012!
