A 20 minute exposure of the night sky in Spain just before the peak of the the 1999 Leonid meteor shower.

The early morning hours of 17 November is the best time to see that the Leonids shower in the United States.
How the Leonids shower
For those in North America, the astronomers are predicting that the best time of the Leonids shower will see, after 1.30 clock ET, and before daybreak on the morning of 17 November 2009, said Michael Bakich the Astronomy.com. The meteor shower can be seen from this November 13-20.

Control peak meteor shower could see more meteors than usual this year due to the rain of shooting stars, the moon at new moon phase, and is not visible from the earth (and) also the unusually dark skies. Experts say that will be 20 to 30 meteors per hour from the U.S., or about half the expected number of the Perseid meteor shower to be visible this summer.

For sky observers in Asia, the meteor shower could be even more impressive. NASA estimates that 200 to up to 300 meteors per hour during Astronomy.com says that number could be up to 500 meteors per hour at peak times, the Leonids.

Background: the comet Tempel-Tuttle and meteorites in the last year, Leonidas
The Leonids shower gets its name because, when you get the meteors in this shower appear to come from the constellation Leo. Dust particle hits the atmosphere of the earth are actually the remnants of debris from Comet Tempel-Tuttle.

Comet Tempel-Tuttle is in a large circular orbit and enters the inner solar system once every 33 years. There are only a few cases in the history of kites, including from the earth to see. According to NASA, although the orbit of Tempel-Tuttle, the Earth does not really occur every time the inner solar system, the cross, leaving a trail of dust, which can eventually be on the path of the earth and lead to future samples of the Earth’s atmosphere, creating a meteor shower.

To find the intensity of the Leonids to country depends on a dusty path, and how close to the center of the whole earth shall waste. In 1999 and 2001 the country was back on the path of comet dust from the visit of the solar system in 1333. Some records over 3000 meteors per hour at peak times during those years.

The mudflow, who was regarded by the world in 2008 as a title from the 1466 Temple-Tuttle. This year the Earth passes through the same route, but perhaps more dust in a wealthy area, so that intense rainfall in 2009 than in 2008.
