Quadrantid Startrail 01-04-14

The Quadrantids (QUA) are a January meteor shower. The zenithal hourly rate of this shower can be as high as two other reliably rich meteor showers, the Perseids in August and the Geminids in December. Yet Quadrantid meteors are not seen as often as meteors in these other two showers, because the peak intensity is exceedingly sharp, sometimes lasting only hours.

 

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. The parent body of the Quadrantids was tentatively identified in 2003 by Peter Jenniskens as the minor planet 2003 EH1, which in turn may be related to the comet C/1490 Y1 that was observed by Chinese, Japanese and Korean astronomers some 500 years ago.

The radiant point of this shower is an area inside the constellation Boötes, not far from the Big Dipper. It lies between the end of the handle of the Big Dipper and the quadrilateral of stars marking the head of the constellation Draco.[5] This meteor shower is best seen in the northern hemisphere, but you can see Quadrantids down to -51 degrees latitude.
