Peak: August 11, 1920, around 22:00 UTC — up to about 100 meteors an hour under a dark sky. The Moon will be 7% lit: a dark sky: a good year for the Perseids. Meteors seem to come from Perseus; the debris is from Comet Swift–Tuttle. The Northern Hemisphere's favorite: warm nights and bright, fast meteors.
