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.
