TAURID METEOR SHOWER

From SpaceWeather:

TAURID METEOR SHOWER:  Earth is passing through a stream of gravelly debris from Comet Encke, source of the annual Taurid meteor shower. Because the debris stream is not very congested, Taurid meteor rates are low, no more than 5 per hour. The special thing about Taurids is that they tend to be fireballs. Check http://spaceweather.com for the latest videos and images of the display, which is expected to peak around Nov. 12th.

TOTAL ECLIPSE OF THE SUN: Scientists and sky watchers are converging on the northeast coast of Australia, near the Great Barrier Reef, for a total eclipse of the sun on Nov. 13/14. For researchers, the brief minutes of totality open a window into some of the deepest mysteries of solar physics.

The sky this weekend will be interesting to say the least.

Taurid Meteor Shower

The Taurids are an annual meteor shower associated with the comet Encke. They are named after their radiant point in the constellation Taurus, where they are seen to come from in the sky. Because of their occurrence in late October and early November, they are also called Halloween fireballs.

Encke and the Taurids are believed to be remnants of a much larger comet, which has disintegrated over the past 20,000 to 30,000 years, breaking into several pieces and releasing material by normal cometary activity or perhaps occasionally by close encounters with the gravitational field of Earth or other planets. In total, this stream of matter is the largest in the inner solar system. Due to the stream's size, the Earth takes several weeks to pass through it, causing an extended period of meteor activity, compared with the much smaller periods of activity in other showers. The Taurids are also made up of weightier material, pebbles instead of dust grains.

Typically, Taurids appear at a rate of about 7 per hour, moving slowly across the sky at about 17 miles per second (27 kilometers per second), or 65,000 miles per hour. If large enough, these meteors may become bolides, with spectacular light shows and even audible sound.

TAURID METEOR SHOWER: The annual Taurid meteor shower is underway and it could be a good show. 2008 is a "swarm year" for the Taurids. Between Nov. 5th and 12th, Earth is due to pass through an unusually dense swarm of gritty debris from parent comet 2P/Encke. When a similar encounter happened in 2005, sky watchers observed a slow drizzle of midnight fireballs for nearly two weeks. Whether 2008 will be as good as 2005, however, remains to be seen. In 2005, the swarm encounter was more central; Earth passed through the middle of the cloud. In 2008, forecasters believe we are closer to the outskirts. How much this will affect the shower, no one knows. The best time to look is during the hours around midnight when the constellation Taurus is high in the sky.
