Peak: December 22, 1922, around 06:00 UTC — up to about 10 meteors an hour under a dark sky. The Moon will be 15% lit: a dark sky: a good year for the Ursids. Meteors seem to come from Ursa Minor; the debris is from Comet Tuttle. A modest shower near the December solstice, for the Northern Hemisphere.
