The International Meteor Organization (IMO) was founded in 1988 and has more than 250 members now. IMO was created in response to an ever growing need for international cooperation of meteor amateur work. The collection of meteor observations by several methods from all around the world ensures the comprehensive study of meteor showers and their relation to comets and interplanetary dust.

You can read about the history, current aims and commissions of IMO. An additional page informs you about how to join the International Meteor Organization. Membership includes a subscription to WGN, the journal of the IMO.

Quadrantids 2009

First results

The Quadrantids are expected to peak on January 3 around 13h UT. The radiant of this shower, in northern Bootes, attains a useful elevation after local midnight and rises higher in the sky towards morning twilight. The waxing crescent Moon sets near local midnight, making 2009 an excellent year to observe the Quadrantids! More information about this shower can be found in the 2009 Shower Calendar. Visual observations can be reported through the Report Form and are highly appreciated. The observations are automatically included in an automated ZHR graph.

Geminids 2008

First results

The Geminids, one of the most spectacular meteor showers, reaches its annual maximum around December 13. Unfortunately the maximum coincides with a full phase of the moon this year, severely hampering optical observations because of the poor darkness of the sky. Observers are nevertheless encouraged to submit their data for analysis. Meteor rates obtained under full moon conditions still teach us more about the activity of this shower than having no data at all.

An automated ZHR graph is made available for this shower.

Leonids 2008

First results

The Leonids have a 'traditional' node time in 2008 on November 17 around 09h UT, though the bright waning Moon close to the constellation of Leo will be a severe problem for observers on any location. In addition to the the traditional maximum, Jérémie Vaubaillon predicts two potential stream encounters, centred on November 17 at 01h32m UT (1466 trail; ZHR ~25-100?) and November 18 at 21h38m UT (1932 trail; ZHR ~20?). Mikhail Maslov proposed that the shower may show a peak with ZHRs ~130 at 00h22m UT on November 17, with meteors brighter than average. Observations around these times, as well as any other moments, would be of great value to test and improve the prediction models. An automated ZHR graph is made available for this shower. Please refer to the short-term meteor activity outlook and the 2008 shower calendar for observing information.
