A rather poorly observed meteor shower, generally regarded as producing low rates (peak ZHR 5–10) around maximum on December 23. The radiant, at RA 14h 28m, dec. +76°, is circumpolar from northern temperate latitudes, lying near the Guardians in Ursa Minor. Higher activity (ZHR perhaps as high as 50) has occasionally been reported, as in 1945, 1982, and 1986. The parent comet is 8P/ Tuttle. Ursid meteors are fairly swift, the brighter ones appearing yellow.
