The International Meteor Organization (IMO) was founded in 1988 and has more than 250 members now. The 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.| International Meteor Organization
During this period, the moon reaches its full quarter phase on Sunday September 7th. On that date it will be located opposite the sun and will lie above the horizon all night long. As the week progresses, the waning gibbous moon will rise later in the evening allowing a small window of opportunity to view between the end of dusk and moon rise...| IMO

Frequently Asked Questions on Visual Observations Contents: I could hardly distinguish the Aquariids or the Taurids. How to note this on the observing form? Which is the best way to determine a reliable value for the limiting magnitude? About 25 per cent of the sky were covered by houses and trees. Does it affect the…| www.imo.net
An easy way to observe meteors visually is what we call the 'counting method.' The observer notes the meteors seen on a tape recorder or just a piece of paper. He gives the estimated magnitude of the meteor and whether or not it belonged to the observed shower (e.g. Perseid or non-Perseid). This met| www.imo.net
