Eclipse on a Polar Day

Explanation: During polar day, in Arctic and Antarctic summer, the Sun stays above the horizon for periods of 24 hours or more. Recorded on December 4, this fisheye timelapse image tracks the Sun in multiple frames as it completes a circle in the summer sky above Union Glacier, Antarctica. Of course on that date, Union Glacier’s sky did grow dark even though the Sun was above the horizon. Captured during the brief period of totality, an eclipsed Sun is at bottom center of the composite view. Near the edge of the total eclipse path across planet Earth, the Moon’s shadow darkens the sky above.

说明: 在北极和南极夏季的极昼,太阳每天24小时都悬在地平面的上方。在这幅12月4日摄于南极洲联合冰川、由多张追踪太阳的鱼眼镜头照片组合而成之延时影像,呈现太阳在该地的夏季天空,一天之中的环绕行迹。而这天在联合冰川的天空,纵然太阳一直悬在地平面上方,黑夜还是降临了。在这幅组合影像的下中方,可见到一轮摄于日全食期间的全食日。在这个位于地表全食带内的位置,月亮的暗影为当地的天空带来短暂的黑夜。
