Explanation: A single exposure made with a camera pointed almost due north on August 12 recorded this bright Perseid meteor in the night sky west of Halifax, Nova Scotia, Canada. The meteor’s incandescent trace is fleeting. It appears to cross the stars of the Big Dipper, famous northern asterism and celestial kitchen utensil, while shimmering curtains of aurora borealis, also known as the northern lights, dance in the night. Doubling the wow factor for night skywatchers near the peak of this year’s Perseid meteor shower auroral activity on planet Earth was enhanced by geomagnetic storms. The intense space weather was triggered by flares from an active Sun.

说明: 8月12日，在加拿大新新斯科舍省的哈利法克斯市西方，一部朝北的相机以单曝光拍下了这颗明亮的英仙座流星。这颗流星稍纵即逝的白炽流星迹，看似贯穿著名的北斗七星，这个在北半球夜空声名颇着、形以水瓢的星官。而在此同时，夜空中有闪烁跃动的帘状极光。对在今年英仙座流星雨极大期附近仰望夜空的人来说，星空的震撼性倍增，因为地球的极光活动，由于受到磁暴的影响也变得更为活跃。而此次剧烈太空天气的源头，则是活跃期的太阳发生了日闪爆发。
