PICTURE OF THE DAY

Atmospheric refraction of the top of the Sun’s disk sometimes creates a vivid green flash if the observer’s horizon is low enough and distant enough.

The green flash

The photographer captured this gorgeous image of the enigmatic green flash while he was at Solana Beach, California. Atmospheric refraction of the top of the Sun’s disk sometimes creates a vivid green flash if the observer’s horizon is low enough and distant enough.
