Peak: December 13, 1922, around 21:00 UTC — up to about 150 meteors an hour under a dark sky. The Moon will be 26% lit: some moonlight, which will hide the fainter meteors. Meteors seem to come from Gemini; the debris is from asteroid 3200 Phaethon. The year's richest shower, with many bright meteors, visible from both hemispheres.
