Peak night by city

For each city: the local time of the peak, and how much of that night is both astronomically dark and free of moonlight.

Why the moon decides a meteor shower

Meteor rates quoted as ZHR assume a perfectly dark sky with the radiant overhead. Real counts fall off fast with sky brightness, and the moon is the one source of sky brightness that is completely predictable years ahead. A full moon near the peak can cut visible meteors by three quarters even under a cloudless sky. That is why the useful question is not “when is the peak” but “where is the moon at the peak” — which is what this page computes.
