Meteor shower should be really good from midnight-4am or so

from http://meteorshowersonline.com/orionids.html :

Moon Forecast for 2009: On the morning of maximum, the moon is about two days from new and will not take away from the meteor display.

The Orionid meteor shower is the second of two showers that occur each year as a result of Earth passing through dust released by Halley's Comet, with the first being the Eta Aquarids. The point from where the Orionid meteors appear to radiate is located within the constellation Orion.

The Orionids generally begin on October 15 and end on October 29, with maximum generally occurring during the morning hours of October 20-22. The Orionids are barely detectable on the beginning and ending dates, but observers in the Northern Hemisphere will see around 20 meteors per hour at maximum, while observers in the Southern Hemisphere will see around 40 meteors per hour. The maximum can last two or three nights, although there is evidence of some fluctuation from year to year.
