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.

Orionids 2015

October brings the first major meteor shower in nearly three months – the Orionids. Pack your winter gear, set your alarm clocks for early morning hours and enjoy this beautiful meteor shower!


When and how to observe?

The Orionids are going to make you get up early! The radiant rises around 10 PM, so no Orionids will be visible in the evening hours. As the radiant rises in the morning hours, so does the number of Orionids and you can expect the highest number in the hour or two before dawn. This year is a good year for the Orionids, as Moon is out of the sky in the morning hours, providing dark skies for observers.

The preliminary estimated trajectory plotted from the witness reports shows the meteor was travelling from the south east to the north west and ended its (visible) flight few miles south of Brighton, UK.
