This gorgeous, high-arching double rainbow signaled the end to a stormy spring day. It was taken at sunset from Samos Island, Greece, a small island in the Aegean Sea. Reddened colors of the primary and secondary bows result from the increased path length of sunlight when the Sun is below the horizon. The brightened area of the sky beneath the primary rainbow occurs when sunlight undergoes a single reflection in raindrops. Note that despite the brightness of the sky near the horizon, the camera is facing opposite of the Sun. Photo taken on April 27, 2014.
