This shower runs annually from October 2 to November 7. It peaks this year on the night of October 21 and the morning of October 22. The Orionids are meteors left behind in the wake of Halley’s Comet. The nearly full 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. Best viewing will be from a dark location after midnight. Meteors will radiate from the constellation Orion, but can appear anywhere in the sky.
