TONIGHT!! Orionid Shower
      #3400824 - 10/20/09 06:46 PM

Info taken from Yahoo...Hope we all get a good,clear showing.
Cheers, Star

The Orionid meteor shower is expected to put on a good show tonight into the predawn hours Wednesday, weather permitting.

This annual meteor shower is created when Earth passes through trails of comet debris left in space long ago by Halley's Comet. The "shooting stars" develop when bits typically no larger than a pea , and mostly sand-grain-sized, vaporize in Earth's upper atmosphere.

"Flakes of comet dust hitting the atmosphere should give us dozens of meteors per hour," said Bill Cooke of NASA's Meteoroid Environment Office.

People in cities and suburbs will see far fewer meteors, because all but the brightest of them will be overpowered by light pollution. The best view will be from rural areas (the moon will not be a factor, so dark skies will make for ideal viewing).

When and how to watch

The best time to watch will be between 1 a.m. and dawn local time Wednesday morning, regardless of your location. That's when the patch of Earth you are standing on is barreling headlong into space on Earth's orbital track, and meteors get scooped up like bugs on a windshield.

Peak activity, when Earth wades into the densest part of the debris, is expected around 6 a.m. ET (3 a.m. PT).

Some meteors could show up late tonight, too. Late-night viewing typically offers fewer meteors, however, because your patch of Earth is positioned akin to the back window of the speeding car.

The Orionids have been strong in recent years.

"Since 2006, the Orionids have been one of the best showers of the year, with counts of 60 or more meteors per hour," Cooke said.



Japanese researchers Mikiya Sato and Jun-ichi Watanabe say activity in recent years is related to debris put in place from 1266 BC to 911 BC, and this could be another good year, according to NASA.

Even if that prediction does not hold, the Orionids will almost surely put on a decent show. Prior to 2006 and going back many years, the Orionids have produced a reliable 15 to 20 meteors per hour at the peak, for skywatchers with dark skies.

As a bonus, this time of year you can expect an additional five to 10 sporadic meteors per hour – those not related to the shower.
