Explanation:
Follow a sunset on a clear day against a distant horizon
and you might
glimpse
a green flash just as the Sun disappears, the sunlight
briefly refracted
over a long sight-line through atmospheric layers.
You can spot a green flash at sunrise too.
Pinpointing the exact place and time to see the rising Sun
peeking above the horizon is a little more difficult though, and
it can be harder still to catch a green flash from
the fainter rising Moon.
But well-planned snapshots did record a green flash at the
Full
Moon's upper edge on June 2nd,
from the Roque de los Muchachos Observatory
on the Canary Island of La Palma.
Looking a little south of due east,
this long telephoto view finds the rising Moon above mountains and
a sea of clouds.
In sunlit profile are the mountaintop
Teide Observatory telescope domes
on the island of Tenerife some
143 kilometers away.
