Early each January, the Quadrantid meteor stream provides one of the most intense annual meteor displays, with a brief, sharp maximum that lasts only a few hours.
The meteors of this first shower of the year radiate from the northeast corner of the constellation of Boötes, the Herdsman, so we might expect them to be called the "Boötids." But back in the late-18th century, there was a constellation here called Quadrans Muralis, the "Mural or Wall Quadrant" (an astronomical instrument). It is one of the many constellation names that have fallen into disuse. Thus, the meteors were christened "Quadrantids" and even though the constellation from which these meteors appear to radiate no longer exists, the shower's original moniker continues to this day.
