Peak: May 5, 1921, around 11:00 UTC — up to about 50 meteors an hour under a dark sky. The Moon will be 7% lit: a dark sky: a good year for the Eta Aquariids. Meteors seem to come from Aquarius; the debris is from Halley's Comet. Debris from Halley's Comet, best from the Southern Hemisphere, before dawn.
