Consequently, most major showers are named after the constellation in which the radiant appears, for examples the Perseids each August and the Leonids each November. There are over a hundred known showers, but only about a dozen major showers are commonly recognized. Meteor observation is important for gaining an understanding of how comets lose material, how it spreads out along the orbit of the comet, the composition of comets, and the relationship between comets and asteroids. Even though most serious meteor observations are now made by radar, the amateur astronomer can still make a contribution. Amateur observations provide important data that helps define meteor swarm orbits and radiant locations, and can help predict major meteor storms.
Several organizations collect amateur observations.
In order for amateur observations to be useful when combined with many others collected from different areas, all must be conducted according to certain guidelines. The most common amateur observation of meteors is simply to count them, but it must be done right. Position yourself comfortably where you can view an unobstructed area of sky for at least an hour or so. Record your viewing period to the nearest minute, including start and stop times, not just the duration. There are charts available to help with this.
