Peak: November 18, 2091, around 15:00 UTC — up to about 15 meteors an hour under a dark sky. The Moon will be 57% lit: some moonlight, which will hide the fainter meteors. Meteors seem to come from Leo; the debris is from Comet Tempel–Tuttle. Every 33 years or so, near its comet's return, the Leonids can storm with thousands an hour. Peak times and rates: the International Meteor Organization's working list.
