GROW Sky Watch

Monday, 12th August 2013 at 8:30pm

Location: Bexhill Beach (Opposite Richmond Road)

This event is in the past.

The Perseid Meteor Shower (Shooting Stars) peaks today with approximately 60 shooting stars every hour!  We may not see many - or any - if it is cloudy though...

Weather permitting, we will meet on our usual beach in Bexhill (directly behind the public toilets) from 8.30pm onwards for sky-watching.  Please bring drinks, something comfortable to sit or lie on & warm clothes as it can get quite chilly on the beach after dark. 

I'll bring the Pizza Base menus (just in case we get peckish lol)

Please call or text 07932 231491 if you need - or can offer - a lift. 

INFORMATION

The Perseids /ˈpɜrsɨdz/ are a prolific meteor shower associated with the cometSwift-Tuttle. The Perseids are so-called because the point from which they appear to come, called the radiant, lies in the constellationPerseus. The name derives in part from the word Perseides (Περσείδες), a term found in Greek mythology referring to the sons of Perseus.

The stream of debris is called the Perseid cloud and stretches along the orbit of the comet Swift-Tuttle. The cloud consists of particles ejected by the comet as it travels on its 130-year orbit. Most of the dust in the cloud today is around a thousand years old. However, there is also a relatively young filament of dust in the stream that was pulled off the comet in 1865.[4] The rate of meteors originating from this filament is much higher than for the older part of the stream.

The Perseid meteor shower has been observed for about 2000 years, with the earliest information on this meteor shower coming from the Far East.[1] Some Catholics refer to the Perseids as the "tears of St. Lawrence", since 10 August is the date of that saint's martyrdom.[5]

The shower is visible from mid-July each year, with the peak in activity being between August 9 and 14, depending on the particular location of the stream. During the peak, the rate of meteors reaches 60 or more per hour. They can be seen all across the sky, but because of the path of Swift-Tuttle's orbit, Perseids are primarily visible in the northern hemisphere. As with all meteor showers, the rate is greatest in the pre-dawn hours, since the side of the Earth nearest to turning into the sun scoops up more meteors as the Earth moves through space. Most Perseids disappear while at heights above 80 kilometres (50 mi).[6] In 2009, the estimated peak Zenithal Hourly Rate was 173,[7] but fainter meteors were washed out by a waning gibbous moon.
