Some images of sunset.
It is the pink to brownish border between the dark shadow band of Earth
and the sky above.
You can see it at the sunset, by looking towards East, when the atmosphere
is cloudless, yet dusty.
The shadow of the Earth is seen as the dark blue part of the sky, and
the red light of the Sun, backscattered by the particles of the air, which
forms the belt itself.
