The Eta Aquarid meteor shower peaks on the 6th, but will be best seen on the night of the 5th around midnight

 

This is one of two meteor showers associated with debris particles deposited over time by comet Halley, the other shower being the Orionids, which peak in late October. Eta Aquarids have a ZHR (zenith hourly rate) approaching 30, however as Aquarius is only just rising in the SE shortly before dawn, observations from the UK are already restricted. Keep a watch on May 24th when a new meteor shower, the 209P-id meteors may occur
