The photo above showing a green flash was snapped at sunset from Paris, France. An animation of a different green flash event was captured by Andrea Console near Rome, Italy. At sunset and sunrise, as a result of atmospheric dispersion, separate images of each spectrum color are generated causing the uppermost rim of the Sun to occasionally flash green. When all but the final portion of the upper green rim has dipped below the horizon, a burst of green light is sometimes visible, particularly when overlooking the ocean. For the flash displayed here, an inferior mirage likely plays a role. Always protect your eyes when observing near the Sun. Photo taken on May 12, 2012.
