Explanation:
Graceful star trail arcs
reflect planet Earth's daily rotation in this
colorful night skyscape.
To create the timelapse composite, on May 12 consecutive exposures were
recorded with a camera fixed to a tripod
on the shores of the Ashokan Reservoir,
in the Catskills region of New York, USA.
North star
Polaris is near the center of the star trail
arcs.
The broad trail of a waxing crescent Moon is on the left, casting
a strong reflection across the reservoir waters.
With
intense
solar activity
driving recent
geomagnetic storms,
the colorful aurora borealis or northern lights, rare to the region,
shine under Polaris and the north celestial pole.
