The observational result shows that this Quadrantid meteor shower occurs between 0000 to 0800 local time in January 4, 2004, with meteor echoes peaking at 0400 local time. Moreover the meteor shower radiant derived from the meteor echoes plane, which is formed by the whole meteor echoes observed by the meteor radar during this shower, accords well with the theoretic radiant of this meteor shower.
从观测结果可以发现此次象限仪座流星雨发生在2004年1月4日的0000-0800LT，其中流星峰值出现在0400LT，而且通过流星雷达观测到的流星雨期间的流星回波平面推测得到的流星雨辐射点也与该流星雨的理论辐射点位置对应非常好。
