The Ursids meteor activity begins annually around December 17 and runs for a week plus, until the 25th or 26th. This meteor shower is named for its radiant point which is located near the star Beta Ursae Minoris (Kochab) in the constellation Ursa Minor. The Ursids were probably discovered by William F. Denning who observed them for several years around the turn of the 20th century. While there were sporadic observations after, the first coordinated studies of shower didn't begin until Dr. A. Bev in 1945. Further observations in the 1970s and ongoing to current have established a relationship with the Tuttle comet, which also has some controversy. Earlier observations described an average radiant of RA=217 deg, DEC=+76 deg, with maximum occurring at a solar longitude of 270.66 deg (about December 22), with the duration being established as December 1724. The Ursids have a particularly narrow stream, prompting veteran meteor observer, Norman W.
