Quadrantids Meteor Shower 3-4.01.2010

The Quadrantid meteor shower is one of the year’s best, producing more than 100 meteors per hour from a radiant near the North Star. This year the shower peaks on Jan. 3rd, 4th. The timing favors observers in western North America and Across the Pacific Ocean.

Although the Quadrantids are a major shower, they are seldom observed. One reason is weather. The shower peaks in early January when northern winter is in full swing. Storms and cold tend to keep observers inside.

Another reason is brevity. The shower doesn’t last long, a few hours at most. Even dedicated meteor watchers are likely to miss such a sharp peak. In his classic book Meteor Astronomy, Prof. A.C.B. Lovell lamented that “useful counts of the Quadrantid rate were made in [only] 24 Januaries out of a possible 68 between 1860 and 1927. … The maximum rate appears to have occurred in 1932 (80 per hour) although the results are influenced by unfavorable weather.”

Quadrantid meteors take their name from an obsolete constellation, Quadrans Muralis, found in early 19th-century star atlases between Draco, Hercules, and Bootes. It was removed, along with a few other constellations, from crowded sky maps in 1922 when the International Astronomical Union adopted the modern list of 88 officially-recognized constellations. The Quadrantids, which were “re-zoned” to Bootes after Quadrans Muralis disappeared, kept their name–possibly because another January shower was already widely-known to meteor watchers as the “Bootids.”
