Major Meteor Showers – from https://www.amsmeteors.org/meteor-showers/meteor-shower-calendar/
The Perseid meteor shower starts activity around July 17 each year and will peak the night of August 12-13. The Moon will be new on August 12 (Wednesday night) so no interference from the Moon as we look for the normal zenithal hourly rates of 30-50.
