Omega sun

On June 26, 2011, Laslo Segi could photographically record this nice moment. “It looked like a second sun rising from the sea, although the sun was just setting.”(1)

“Some time later I learned that it was a lower mirage, that means that the sky is reflected upwards by a thin layer of warm air above the ground.”

This is caused by air layers of different temperature. At the boundary surface, light is totally reflected causing these phenomena. This phenomenon, however, is called “Omega-sun”, because the shape of the sun is similar to the Greek letter omega.
