象限儀座流星雨
Sign in to saveThe Quadrantids (QUA) are a meteor shower that peaks in early January and whose 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, 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 magnitudes between 3.0 and 6.0.

象限儀座流星雨(QUA)是一月的流星雨。這場流星雨的天頂每小時流星率(ZHR)可以像8月的英仙座流星雨和12月的雙子座流星雨一樣高,達到120。但是,持續的時間較短,通常只有數小時。此外,流星的視星等較為黯淡,多數僅在3〜6等之間。 雖然這個流星雨的輻射點位於牧夫座的區域內,但名稱卻來自一個现已經廢棄的星座——象限儀座,它有一部分所属于現在的牧夫座。
