It was one of the quietest nights of aurora in weeks. Even so, in northern- Iceland during last November, faint auroras lit up the sky every clear night. The featured 360-degree panorama is the digital fusion of four wide-angle cameras each simultaneously taking 101 shots over 42 minutes. In the foreground is serene Lake Myvatn dotted with picturesque rock formations left over from ancient lava flows. Low green auroras sweep across the sky above showing impressive complexity near the horizon. Stars far in the distance appear to show unusual trails — as the Earth turned — because early exposures were artificially faded. Follow APOD on: Facebook, Google Plus, or Twitter

在上個十一月，冰島北部的夜空是一個寧靜的地方，儘管最近幾周的極光活動相對較少，但每個晴朗的夜晚，微弱的極光仍然點亮了天空。這幅360度全景圖是四臺廣角攝影機同時拍攝101張照片，並經過42分鐘的數碼融合而成。前景是寧靜的米湖（Lake Myvatn），湖面上散佈著古老熔岩流留下的迷人岩石。在天際線附近，低低的綠色極光在天空中劃過，展現出驚人的複雜性。由於早期的曝光經過人工淡化，遙遠的星星似乎顯示出不尋常的光跡——因為地球正在自轉。
