Orionid meteor shower peaks Oct. 20-21, 2012

Oct 18, 2012

As it does each year, early fall brings crisper air, turning leaves, and the Orionid meteor shower. This year's best viewing will be in the several hours around midnight October 20 and before dawn on October 21, according to the editors of StarDate magazine.

At its late-night peak, this year's shower is expected to produce around 25 meteors per hour. The first-quarter Moon will set around midnight, so its light will not interfere with the celestial show.

Orionid meteors appear to fall from above the star Betelgeuse, the bright orange star marking the shoulder of the . They are not associated with this star or constellation, but instead are leftover debris from Halley's Comet. The Orionid meteors recur each year when Earth passes through the comet's debris trail.

For your best view, get away from city lights. Look for state or city parks or other safe, dark sites. Lie on a blanket or reclining chair to get a full-sky view. If you can see all of the stars in the Little Dipper, you have good dark-adapted vision.
