2018 Quadrantid Meteor Shower

   The annual Quadrantid Meteor Shower reaches its peak Wednesday morning January 3rd officially at 14:19 UT (9:14 am 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 ZHR (average hourly rate) for this meteor shower ranges from 60 to several hundred. Best time for viewing is before sunrise as your part of the Earth is rotating toward the east sort of putting you headfirst into the meteor shower. To find the radiant for this meteor shower look for the stars of the Big Dipper and then look below the end stars in the handle.

   Adding to the thrill of seeing a shooting star are the the planets Jupiter and Mars about 1o apart and closing in on a very close 0.2o separation on the 6th. Look closely and you may see Zubenelgenubi, one of the stars making up Libra the Scales. All three fit comfortably within the field of view of binoculars and contrast nicely in their respective apparent magnitudes (magnitudes shown on graphic).

Boötes the Herdsman

   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.
