The '''Quadrantids''' ('''QUA''') are a [[meteor shower]] that peaks in early January and whose [[radiant (meteor shower)|radiant]] lies in the constellation [[Boötes]]. The [[zenithal hourly rate]] (ZHR) of this shower can be as high as that of two other reliably rich meteor showers, the [[Perseids]] in August and the [[Geminids]] in December,<ref name="amsmeteors.org">{{cite web |url=http://www.amsmeteors.org/meteor-showers/meteor-faq/#7 |title=Does the published meteor rate for a shower really represent what I should expect to see? |publisher=[[American Meteor Society]] |access-date=2012-12-29}}</ref> yet Quadrantid meteors are not seen as often as those of the two other showers because the time frame of the peak is exceedingly narrow, sometimes lasting only hours. Moreover, the meteors are quite faint, with mean [[apparent magnitude]]s between 3.0 and 6.0.
