	Meteor Showers
		Meteor Showers occur due to the Earth passing through or near the path of a comet.
		Because all meteors within a shower are falling toward Earth in parallel paths, to the observer this creates the illusion that they are all originating from one spot in the sky (similar to the way two railroad tracks seem to come together at the horizon).
		The constellation that a given meteor shower's radiant is in, is the constellation that the shower is named after.

		The average meteor from this shower is faint and therefore difficult to photograph.
		This shower is invisible in the Southern Hemisphere.

	AMS Meteor Showers page
		Meteor showers are usually named for the constellation in which their radiant lies at the time of shower maximum.
		Sporadic meteors are those random meteors not associated with a particular shower; they are the random detritus left over from the creation of the solar system or are old dispersed debris not recognizable today as shower meteors.
		Meteor activity is best seen in the absence of moonlight so showers reaching maximum activity when the moon is less than 10 days old or more than 25 are much more favorably observed than those situated closer to the full moon.

	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.

		Following the wholly unexpected strong return of this shower in 1998, we are delighted to reintroduce the June Bootids to the Working List of visual meteor showers this year, and to encourage all observers to routinely monitor the expected activity period in case of future outbursts.

	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.

	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.

	Skywatch - Leonid Meteor Shower - November 2001
		The Leonid meteor shower is due to hit on the morning of November 18th for North America.
		Meteors are created when sand- or pebble-size grains strike Earth's atmosphere at high speed and create streaks of superheated air along their paths.
		The meteors should be visible across the sky, appearing to radiate from the east, in the direction of the constellation Leo that gives the shower its name.

	Perseid FAQ (Site not responding. Last check: 2007-10-22)
		The number of meteors you will detect further depends on the mean length of the meteor trails involved (which relates to the population or mass index), as longer trails offer greater probabilities of scattering from any one location.
		Although ideally meteor data should be collected at all times when conditions permit throughout the year, such protracted monitoring is often not possible, thus the Calendar provides a ready means of helping to determine when a particular effort may be most usefully made for those with a restricted observing schedule.
		The only shower likely to produce difficulties in plotting terms is the Southern Delta-Aquarids near their peak, though the time of their maximum is rather uncertain, and activity may well be reasonably good for a night or two to either side of the predicted date.

	IMO Meteor Shower Calendar 1998 \| International Meteor Organization
		Even this can never be a complete list of all meteor showers, since there are many showers which cannot be properly detected visually, and some which only photographic, radar, telescopic, or video observations can separate from the background sporadic meteors, present throughout the year.
		Meteor activity picks up towards the April-May boundary, with showers like the Lyrids, p-Puppids and h-Aquarids, and only this latter source suffers from moonlight this year.
		Ecliptical minor shower activity reaches what might be regarded as a peak in early to mid November, with the Taurid streams in action (the Southern Taurid maximum will be lost to bright moonlight this year, but something of the Northern peak should still be seen).

	IMO Meteor Shower Calendar 2002 \| International Meteor Organization
		Meteor activity picks up towards the April-May boundary, with shower peaks from the badly-moonlit Lyrids (due on April 22, 10:30 UT, but it may extend for several hours around this time based on results from recent years) and the pi-Puppids (expected towards April 23, 21h UT).
		The Perseids were one of the most exciting and dynamic meteor showers during the last decade, with outbursts at the shower's primary maximum producing EZHRs of 400+ in 1991 and 1992.
		However, we have still listed this time here, allowing for the annual shift of aboubt +0.05° in lambda the peak had shown from 1991-1999, because confirming the peak's absence at present is as important as observing it again.

	Meteor Showers List
		The list is based on the 1995 revision of the International Meteor Organization's (IMO's) Working List of Visual Meteor Showers, itself based on the most accurate global datasets ever collected, from 1988-1995.
		As we have discovered particularly during the last decade, meteor showers are not fixed things, but are in a constant state of flux and change, some changing faster than others.
		The two showers give low rates, but occasional fireballs spice up their prospects, and in some years (as last in 2005) these can be especially prevalent in late October to early November (mostly moonless, but nothing unusual is predicted this time).

	IMO Meteor Shower Calendar 2004 \| International Meteor Organization
		The year sees two of the "big three" major shower peaks - the Perseids and Geminids - mostly or entirely free from moonlight interference, but the third, the Quadrantids, are badly moonlit, along with the alpha-Centaurids, eta-Aquarids, and Southern delta-Aquarids.
		We appreciate that this is not practical for many observers, and this Calendar was devised as a means of helping observers deal with reality by highlighting times when a particular effort may most usefully be employed.
		The majority of data available are for visual shower maxima, so this must be borne in mind when employing other observing techniques.

		This point, called the radiant, is really an optical illusion – the meteors are moving along parallel paths, but appear to come from a single point, just as a stretch of parallel railroad tracks will appear to meet at a point on the horizon.
		Outbursts, when the rates of visible meteors are much higher, have been seen in a number of years including, in recent times, 1803 (when observers counted 700 meteors per hour), 1922, and 1982.
		The Lyrid meteor shower peaks on the morning of April 22 – a typical peak for the Lyrids is about 15 shooting stars an hour, or one every few minutes.
