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.
