  Perseids 2006: prediction of activity
Perseids are one of the most famous meteor showers.
Perseid maximum in 2006 will be moonlit as the Moon passes its full phase on 9 August.
Perseids 2006 are expected to show a rather moderate background maximum with ZHR not exceeding 80-90 meteors.

 CNN.com - Perseid meteor shower peaks overnight - Aug 11, 2004
This photograph of a Perseid meteor was taken in August 2000 in South Dakota.
Perseids can appear anywhere in the sky, but if traced back they will appear to emanate from a point in the constellation Perseus, which rises in late evening in the East and is high overhead in the wee hours before sunrise.
The Perseids are the result of stream of debris in space laid down by comet Swift-Tuttle, which orbits the Sun every 130 years and spends most of its time in the far reaches of the solar system.

Meteor showers can be seen when (The 3rd planet from the sun; the planet on which we live) Earth moves through a meteor stream.
The cloud is comprised of particles ejected by the comet as it passed by the (A typical star that is the source of light and heat for the planets in the solar system) Sun.
Because of the positioning of Swift-Tuttle's orbit, Perseids are mostly visible on northern (Half of the terrestrial globe) hemisphere.

 The Perseids
Perseids is the most well known and most active contemporary meteor shower.
In the Medieval period Perseids got the name "St Laurence tears" for the name of the holiday that is celebrated in the time of the meteor shower maximum.
For such an abundant meteor shower as Perseids are, especially in the day of maximum, it is hardly possible to determine the radiant coordinates exactly enough while using the pictures with only two meteor images.

 The Perseids : Comets, meteors and asteroids : Astronomy & space : Fact files : Learning : National Maritime Museum
The Perseids were the first meteor shower to be connected to a comet when astronomer Giovanni Schiaparelli noted the similarity between their orbit and the Comet Swift-Tuttle that was observed in 1862.
Even in quiet years, the Perseids have a reputable activity rate that can exceed 100 meteors per hour from a dark site - the rate tends to be highest towards dawn when the observer is on the side of the Earth moving directly into the cloud of meteoroid debris.
Perseid meteors also tend to be bright so in many ways the shower is ideal for anyone wishing to see their first 'shooting star' – an observer watching the early morning skies will almost certainly see a number even over a period of thirty minutes.

 IMO Results: Perseids 1995 and 1996
Traces of the outburst Perseids situated roughly 12 hours before the regular Perseid maximum near sol=140° were found in the 1988 and 1989 Perseid analyses [2].
Although the analysis of the 1996 Perseid return is based only on a part of the entire data becoming available later, the results should be expected to be quite close to the final values.
The ascending node of the comet 109P/Swift-Tuttle is at 139.44° [6], hence the 1992 passage was the closest to the orbit of the Perseid parent comet.

 SPACE.com -- Viewer's Guide: Perseid Meteor Shower Peaks Aug. 11-12
Perseid meteors emanate from the constellation Perseus, which rises above the horizon in late evening this time of year (shown on this map) and is high overhead during the predawn hours.
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.
Perseid meteors can appear anywhere in the sky, but if traced backward, they all point toward Perseus, which is know as the shower's radiant.

This spectacular event is known as the Perseid meteor shower, and it usually provides the best meteor show of the year.
With mostly Moon-free conditions surrounding the Perseid peak (the waxing crescent sets at around 10:50pm on August 12), this shower should be attractive to new meteor counters.
The Perseid meteor shower in August of each year is associated with Comet Swift-Tuttle, a well-known comet that has a 134-year orbit and was last near the sun in 1992.

The result was a massive reverse exodus as Perseids from throughout the Known Worlds retreated to their ancestral homeworld of Ugroth.
Ugroth, once nearly abandoned as the Perseids spread out among the stars, is now home to nearly 150 billion Perseids, making it the most densely populated world in known space.
Perseids are bisexual by nature, with each individual capable of both fertilizing another and gestating young itself.

Perseid meteor activity should continue nightly for at least the next week or so, but the intensity and number of shooting stars fall off rapidly after the peak.
This year's Perseids are flashier than last year's because the moon is a mere crescent — which poses relatively little competition for the celestial streaks.

 CNN.com - Summer shower on tap, from space - August 8, 2002
The Perseids slowly have increased in number in recent weeks and are expected to culminate overnight Monday and Tuesday with up to 80 "shooting stars" an hour.
The Perseid meteors come from dust-size grains left behind by comet Swift-Tuttle, which every 130 years flies into the inner solar system.
Rather than leaving behind a bloblike carcass, the Perseids disappear into a blaze of streaking light, incinerated by intense friction as they smack into the sky at speeds of about 37 miles per second (60 kilometers per second).

Although a few weaker-than-normal years occurred during the 1920's, the Perseids regained their consistency thereafter, and, except for abnormally high rates of 160 and 189 during 1931 and 1945, respectively, nothing unusual was observed up through 1960.
One of the most recent examples of the complexity of the Perseid meteor shower was revealed in three studies of the radiant conducted during 1969 to 1971, by observers in the Crimea.
The Gamma Perseids mainly occur during August 11 to 16 from an average radiant of RA=41 deg, DECL=+55 deg.

 Perseids - Slackerpedia Galactica
The Perseids are a meteor shower cause by Earth passing through the debris field of Comet Swift-Tuttle.
The Perseids are a very reliable meteor shower, usually with a zenith hourly rate (ZHR) of around 100-120.
The Perseids are often covered by the media as they serve as a visible introduction for aspiring astronomers.

 Perseids 2004
Brighter Perseids, particularly, often leave behind brief persistent ionisation trains which result from ionisation on the high atmosphere produced by the meteoroids’ high entry velocity of 60 km/sec.
Enhanced Perseid activity was noted around the time 109P/Swift-Tuttle’s 1992 perihelion, this taking the form of short duration ‘spikes’ of high rates ahead of the regular, established maximum.
Indeed, computer modelling of the Perseid meteor stream by Esko Lyytinnen and Tom Van Flandern suggests that enhanced activity comparable to that in 1980 may occur early on August 11-12, accompanied by a short-lived peak of faint Perseid activity: observations are needed to check this theory!

Although the Perseids officially begin in late July, the shower builds rather slowly in intensity until there is a series of sharp peaks in activity near mid-August.
The Perseids were the first meteors ever associated with a particular comet.
The proximity of the comet once again caused an increase in Perseid activity and, in August 1993, observers in Central Europe were treated to 200 to 500 meteors per hour.

The best known meteor shower is the Perseid shower, and it peaks August eleventh.
