by Orionid meteors fly each year between about October 2 to November 7.
That’s when Earth is passing through the stream of debris left behind by Comet Halley, the parent comet of the Orionid shower.
The Orionids usually put out the greatest number of meteors in the few hours before dawn. And the expected peak morning in 2021 is October 21.
Bad news for Orionid fans this year, though. The 2021 full Hunter’s Moon will be October 19-20.
That means moonlight will flood the sky all night, or nearly all night, during the Orionids’ peak.
But you might see an Orionid meteor at any time during October, assuming you’re a dark location, with a sky free of moonlight.
