On May 5 and 6 (peak), 2017 before dawn, is the Eta Aquariids meteor shower.
The Eta Aquariids meteor shower is debris from Halley’s Comet.
The best time to watch these meteors is in the early morning hours, before the beginning of morning twilight (see below).
Give yourself at least an hour of viewing time for watching as there will be lulls. Remember that it may take up to 20 minutes for your eyes to adjust to the dark.
Some meteors may fly in the dark hour before dawn for a few days before and after May 5/6.
