The annual Quadrantid Meteor Shower reaches its peak Saturday morning January 4th officially at 4 UT (Friday January 4th 10:00 pm CST). The Quadrantids are one of the best meteor showers of the year but does not get much attention possibly because it’s winter in the northern hemisphere, and this area of the sky is not easily seen from south of the equator.The radiant is the area from where the meteors seem to radiate outward from. Meteor showers owe their name to the constellation region the radiant is located within, and as this graphic shows the radiant is within the boundary of the constellation Boötes the Herdsman.
So why the name Quadrantids?
On some of the older star charts there is a now ‘extinct’ constellation called Quadrans Muralis, the Mural. This was a constellation located between Boötes and Draco the Dragon that was created in 1795 by French Astronomer Jérôme Lalande. It is a picture, or mural, of a Quadrant that had been used to map the stars. The Quadrantids Meteor Shower was named for the no longer used constellation.
