  AMS Meteor Shower FAQ
Meteor showers are usually named for the constellation in which their radiant lies at the time of shower maximum.
Meteor storms are generally caused by young meteor streams, in which the majority of the streams' mass is still concentrated along that portion of the orbit occupied by the parent comet.
Meteor storms occur when the Earth crosses the orbit of the meteor stream, at the same time that the main mass of the young meteor stream is crossing the orbit of the Earth.

meteor shower, increase in the number of meteors observed in a particular part of the sky.
The trails of the meteors of a meteor shower all appear to be traceable back to a single point in the sky, known as the radiant point, or radiant.
A shower is named for the constellation in which its radiant is located, e.g., the Lyrids appear to come from a point in Lyra, the Perseids from Perseus, and the Orionids from Orion.

 Meteor shower - Wikipedia, the free encyclopedia
Most meteors seen in meteor showers are caused by particles smaller than a grain of sand.
Because meteor shower particles are all traveling in parallel paths, and at the same velocity, they will all appear to radiate from a single point in the sky to an observer below.
For instance, Mars is known to have meteor showers, although these will be different than the ones seen on Earth because the different orbits of Mars and Earth will intersect with orbits of comets in different ways.

 Meteors and Meteor Showers
That meteors in meteor showers appear to radiate from a single point in the sky is an optical illusion, as illustrated in the figure on the right.
Meteor showers often vary in intensity from year to year, presumably reflecting details of encountering the orbit of the parent comet.
As an historical note, the 1833 Leonid shower in a certain sense marked the birth of the modern study of meteors, because attempts to explain the remarkable outburst eventually produced the realization that the Leonids are correlated with the periodic comet P/Tempel-Tuttle.

 Leonid Meteor Shower 2006 -- When, Where, and Why - Planetary News | The Planetary Society
However, unlike a typical meteor shower, astronomers are predicting an unusual "outburst" of meteor activity late November 18 - early November 19 (the date it occurs depends on where you live).
Traditionally, the meteors that make up this shower are much smaller and therefore fainter when they hit Earth's atmosphere and burn up.
Meteor showers offer a great excuse to sit outside and enjoy nature -- just be sure to pack warm clothes, these November nights get chilly.

 Big meteor shower Wednesday night - CNN.com
Studies of past displays show that this shower has a reputation for being rich both in slow, bright, graceful meteors and fireballs as well as faint meteors, with relatively fewer objects of medium brightness.
Because Geminid meteoroids are several times denser than the cometary dust flakes that supply most meteor showers and because of their relatively slow speed with which they encounter Earth (22 miles/35 kilometers per second), Geminid meteors appear to linger a bit longer in view than most.
A final point to note are that Geminids stand apart from the other meteor showers in that they seem to have been spawned not by a comet, but by 3200 Phaeton, an Earth-crossing asteroid.

 Leonid MAC '99 - FACTS on meters and meteor showers   (Site not responding. Last check: 2007-11-05)
Meteors are better known as "shooting stars": startling streaks of light that suddenly appear in the sky when a dust particle from outer space evaporates high in the Earth's atmosphere.
For example, a Leonid meteor of magnitude +5, which is barely visible with the naked eye in a dark sky, is caused by a meteoroid of 0.5 mm in diameter and weights only 0.00006 gram.
The color of a meteor is an indication of its composition and the excitation temperature: sodium atoms give an orange-yellow light, iron atoms a yellow light, magnesium a blue-green light, calcium atoms may add a violet hue, while silicon atoms and molecules of atmospheric nitrogen give a red light.

 Meteor Showers in 2005-2006
Although meteors can be large, the typical size of the particle that produces such a lovely display in our sky ranges from about the size of a grain of sand to the size of a small pebble.
The radiant of a shower is the point in the sky from which meteors would appear to come if you traced their visible paths backward.
Like sporadic meteors, meteors from a shower can be seen in any part of the sky, but if you take the ending point of the meteors' trails and trace them backward through their starting points, the place where these paths converge is the radiant for that shower.

 Meteor Shower, Meteor Showers, Meteor, Meteors, Asteroids, Comets And Meteors at SPACE.com
Meteor showers occur as the debris traveling in the path of its parent comet enters the Earth’s atmosphere.
This is why a meteor shower is often named by the constellation from which its meteors appear to fall.
For example, the Perseid meteor shower was named after the constellation Perseus because its meteors appear to be falling from a point in this particular region of the sky.

 meteorobs - Meteor Storms (Leonids)
Meteor showers are annual events where more meteors than usual can be seen over a given period of nights, all appearing to point back to (or "radiate from") a particular point in the sky.
These meteor showers actually occur when the earth in its orbit around the sun, is passing through a particular band or "stream" of meteoroid dust particles: these meteoroid streams are usually the debris trails of periodic comets, or in some cases (i.e., the Geminids) asteroids.
If however a shower is normally a weaker event, for example the Ursids of late December, then its "outburst" may be only noticeable as a significant enhancement to careful meteor watchers, who are used to observing meteors in general and that shower in particular.

Meteors are streaks of light in the sky caused by blazing pieces of dust drawn into the Earth's atmosphere from near space.
Astronomers expected a faint, extra surge of meteors would occur on 11 August at 2200 BST due to a filament of dust that boiled off 109P/Swift-Tuttle in 1862 and is only now crossing the Earth's orbit.
Mr Bone estimated that about one in 500 to 1,000 meteors during the Perseid showers are as bright in the night sky as the planet Venus.

 Leonid Meteor Shower makes its Annual Return   (Site not responding. Last check: 2007-11-05)
The Leonids meteor shower will return on November 19th and although it won't produce a meteor storm like last year, it will still be worthwhile to go outside and observe.
Meteor showers are also associated with a comet, in this case it's comet Tempel-Tuttle, which sweeps through our part of the Solar System every 33 years and then returns out beyond Uranus.
As mentioned earlier, the average Leonid meteor is moving at 160,000 mph and that is fast enough to compress the air in front of it, pushing it out of the way like the wake of a boat.

 The Quadrantid Meteor Shower   (Site not responding. Last check: 2007-11-05)
The Quadrantid meteor shower is one of the year's best, regularly producing 50 to 120 meteors per hour.
The shower's radiant is located high in the northern sky, so observers in the southern hemisphere, where the weather might be more favorable, see almost nothing.
The source of the Quadrantid meteor shower was unknown until Dec. 2003 when Peter Jenniskens of the NASA Ames Research Center found evidence that Quadrantid meteoroids come from 2003 EH1, an "asteroid" that is probably a piece of a comet that broke apart some 500 years ago.

 The Leonids
The meteors radiate from Leo, the zodiac constellation associated with the astrological sign of the lion for those born in August.
The radiant point of the shower is in the "sickle" of Leo at a right ascension of 10h 14m and a declination of +22 degrees.
Since, visually, meteors look like a star streaking across the sky, they are commonly called "shooting stars." If a meteor is sufficiently large, part of it may survive and strike the Earth, in which case it is called a meteorite.

 Your guide to the Perseid meteor shower - Space.com - MSNBC.com
The Perseid meteor shower is so named because the flashes appear to radiate from the constellation Perseus, shown on this sky chart.
The August Perseids are among the strongest of the readily observed annual meteor showers, and at maximum activity nominally yield 50 or 60 meteors per hour.
About five to 10 of the meteors seen in any given hour will not fit this geometric pattern, and may be classified as sporadic or as members of some other (minor) shower.

The meteor showers of those years approached the intensity of "meteor storms," a threshold generally marked when viewers can see a thousand meteors an hour.
They note, however, that predicting meteor shower intensity is not always an exact science.
Observations of this storm, coupled with those of succeeding years, allowed scientists to theorize that the meteors originated from a cloud in space and later to establish the shower's radiant, or apparent point of origin.

Occasionally, though, intense meteor displays fill the sky with tens, hundreds, or even thousands of of meteor trails.
Many meteor showers can be predicted, as they repeat every year when the earth passes through the path of a comet.
Known meteor showers are usually named for the constellation from which the meteors seem to originate, called the radiant, or for the comet responsible for the shower.

There are also a lot of interesting bits of information associated with the Perseids and its parent comet, Swift-Tuttle, which with each pass through the inner solar system sheds some of its skin in the form of dust and other small chunks of debris.
Some large meteors splatter, causing a brighter flash called a fireball, and sometimes an explosion that can often be heard from the ground.
For this reason, the Perseids and other meteor showers (and also random shooting stars in general) are usually best viewed in the predawn hours.
