Maine Anticrepuscular Rays
Steve Kluge took the image and he describes the scene..
"We [were on] the southern coast of Maine where we were treated
to an incredible view of the rising nighttime sky over Nubble Light
near York Beach.
nice sea breeze had developed earlier in the day, and a small scattering
of cumulus clouds developed in the air rising over the warm land
The rays of light and dark that appear to converge
near the horizon are anticrepuscular rays, the darker areas are
actually the parallel shadows of those clouds cast against the sky
by the setting sun. Perspective causes the apparent convergence
at the anti-solar point in the sky.
The band of pink sky that the almost full moon seems
to float on is called the "Belt of Venus", and it is the last bit of
sky to be lit by the red rays of the sun. Just below the Belt,
the dark sky of the Earth's shadow is rising, and both aspects are
nicely reflected off the water, too! "
