The year 2009 in images and words
Actually there are three succesfull campaigns to mention in 2009: the Quadrantids, Perseids and Geminids. The Lyrids largely disappeared behind the clouds, just like the Leonids and Orionids. The Quadrantids showed unexpectedly strong activity with ZHR's two to three times higher than expected. Michel Vandeputte came over from Belgium to escape the bad weather.

The Perseids were observed from my vacation address in Vaison La Romaine, southern France. It resulted in 35 hours of observations and 1200 meteors. Best night was 12/13 August with another unexpected outburst, ZHR's up to 130 and many bright meteors. This time a dusttrail left behind by comet 103P/Swift-Tuttle in 1348 and a structure called filament are responsible for this outburst.


Picture 3: Evening outburst of bright Perseids. The brightest one was a long flaring -6 Perseid.


Picture 4: 11/12 august 2009, a bright Capricornid (magn. -4) and 2 Perseids.

The Orionids went down in clouds and rain. Only the night 24/25 October would be observed from Ermelo, I observed declining Orionid activity. When the first reports started to appear about high Orionid activity, Carl Johannink and I made an attempt to escape from the bad weather en drove to Grevesmühlen to observe the Orionids (20/21 October). It was a moderate succes, after 2,5 hours the sky clouded out. But we observed clearly enhanced Orionid rates (ZHR 40).
The Leonids had their last outburst of the new series. We had a clear night in the Netherlands, but due to the low radiant position, there was just a small part visible of this outburst.
The biggest meteor stream for 2009 were the Geminids. This could and should be observed. So it was again a campaign ala 2007. A last minute ticket to clear skies! We ended up on a camping on a farm near Castelo de Vide in Portugal. There we observed succesfully the brilliant Geminids.
All in all, 2009 is a good meteor year with more than 144 hours effective observing time and 3606 meteors.
