Peak: December 21, 1917, around 23:00 UTC — up to about 10 meteors an hour under a dark sky. The Moon will be 58% lit: some moonlight, which will hide the fainter meteors. Meteors seem to come from Ursa Minor; the debris is from Comet Tuttle. A modest shower near the December solstice, for the Northern Hemisphere.
