The Orionids meteor shower is an annual meteor shower that runs from October 2 to November 7. It peaks this year on the night of October 21 and the morning of October 22. The second quarter moon will block some of the fainter meteors this year, but the Orionids tend to be fairly bright so it could still be a good show.
This meteor shower can be classified as an average shower producing up to 20 meteors per hour at its peak. It is produced by dust grains left behind by comet Halley, which has been known and observed since ancient times. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Orion, but can appear anywhere in the sky.
It is possible that some years see an average of 50-70 meteors per hour.
It is worth noting that if unable to see the Perseid Meteor shower, there is enough time to plan for seeing the Orionids. But this requires the weather in the Pacific Northwest to not be cloudy.
