* Estimate for a dark rural sky, taking the radiant’s altitude and the Moon into account. From a city you will see far fewer. Local time for each city.

ZHR: meteors per hour with the radiant overhead and a perfectly dark sky. In practice you see fewer.

How to watch

No telescope or binoculars needed. Find a dark spot away from lights, lie back looking at the highest part of the sky and give your eyes 20 minutes to adapt. Meteors appear in every direction; their trails point back to the radiant.
