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 become a member the International Meteor Organization. Membership includes a subscription to WGN, the journal of the IMO.

Perseids 2011

Perseids radiant

The Perseids are one of the most exciting meteor showers; producing fast-moving shooting stars throughout July and August. Based on IMO observations from recent years, we expect a peak of roughly 100 meteors per hour to occur in the night of August 12-13. Unfortunately, the vast majority of these meteors will not be visible due to the bright light of the full moon which also occurs on August 13.

Nevertheless, we encourage visual observations to be made according to the standard procedure and submitted through the online report form. Such observations will automatically be included in the ZHR activity graph below.

eta-Aquariids 2011

The eta-Aquariids are expected to peak on the evening of 2011 May 6 (ZHR ~60). The radiant of this shower in Aquarius rises rather late in the night. Northern obserevrs should use the last morning hour, mid-southern hemisphere observers have a longer observing window. Visual observations can be reported through the Report Form and are highly appreciated. The observations are automatically included in an automated ZHR graph. Note that meteor numbers far from the maximum may be very low and lead to highly uncertain ZHRs.

Lyrids 2011

The Lyrids are expected to peak on the evening of 2011 April 22 (ZHR ~20). The radiant of this shower, between Lyra and Hercules, rises during the night. Watches can be usefully carried out from about 22h30m local time onwards from mid-northern sites, but only from well after midnight from the mid-southern hemisphere. Visual observations can be reported through the Report Form and are highly appreciated. The observations are automatically included in an automated ZHR graph.
