Peak: May 5, 1917, around 10:00 UTC — up to about 50 meteors an hour under a dark sky. The Moon will be 97% lit: a bright Moon, which will wash out all but the brightest meteors. 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.
