About Quadrantids

The Quadrantids are an easily visible January meteor shower. The radiant of this shower is an area inside the constellation Botes. The name comes from Quadrans Muralis, an obsolete constellation that is now part of Botes. It lies between the end of the handle of the Big Dipper and the quadrilateral of stars marking the head of the constellation Draco. Adolphe Quetelet of the Brussels Observatory discovered the shower in the 1830s, and shortly afterward it was noted by several other astronomers in Europe and America. The peak intensity is exceedingly sharp: the meteor rates exceed one-half of their highest value for only about 8 hours (compared to two days for the August Perseids). This means that the stream of particles that produces this shower is narrow and apparently deriving from and within the last 500 years from some orbiting body.
