Annual Perseid meteor shower set to peak

The annual Perseid meteor shower will reach its peak from the night of Aug. 12 to the early hours of Aug. 13, it's been learned.
(Mainichi Japan) August 11, 2010As a new moon fell on Aug. 10 this year, the meteor shower is expected to be observed under good conditions with clear skies free of moonlight -- if it doesn't rain.
"In the night skies above suburban areas, where the fourth-magnitude star can be seen, 12 to 15 meteors will shoot per hour," a National Astronomical Observatory of Japan (NAOJ) official says.
The Perseid meteor shower is one of the three largest meteor showers seen every year. Perseid meteors can be viewed across the skies as they appear from a radiant point located between the constellations Perseus and Cassiopeia. There are usually many bright meteors, and some leave an afterglow that remains visible for a few seconds.
"It will be interesting to observe the meteor shower, focusing on what percentage of meteors leave an afterglow," says Mikiya Sato, a Public Relations Center official at NAOJ.
To report the number of meteors you observed, log on to the NAOJ's "Perseid meteors 2010" campaign Web site: http://naojcamp.nao.ac.jp/phenomena/20100811/ or its mobile site: http://naojcamp.nao.ac.jp/i/phenomena/20100811/
Reports will be accepted from the night of Aug. 11 to the morning of Aug. 15.
According to the Japan Meteorological Agency, due to Typhoon No. 4, there is a chance of cloudy weather or intermittent showers in many places in Japan on the nights of Aug. 11 and Aug. 12, but there will be intervals of clear weather on the night of Aug. 13 throughout the country except some parts of the Hokuriku and Tohoku regions.
