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. Becvar 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 17-24.
The Ursids have a particularly narrow stream, prompting veteran meteor observer, Norman W. McLeod, III (Florida) to comment that the Ursids "must be a compact stream like the Quadrantids. You have to be within 12 hours of maximum to see much."
