An Orionid meteor streaks across the sky, with the bright three-star belt of the constellation Orion, as well as the Orion nebula (center right) shine in the background.

The peak of this shower is in October 21, 2012, before dawn. The waxing crescent moon setting before midnight on October 20 will provide quite dark night. The best time for viewing for these fast-streaking Orionid meteors is between midnight and dawn the next few mornings.
They seem to come from the constellation Orion. The radiant is north of Betelgeuse, Orion’s bright star of red hue.
The Orionids have a broad and irregular peak that is not predictable easily. On a dark, moonless night, the Orionids exhibit about 15 meteors in one hour. These fast-moving meteors occasionally leave persistent trains and bright fireballs.
