Green Flash Poster #1

Product Information

The infamous and illusive Green Flash.  A green flash can appear just as the last sliver of the setting sun dips below the horizon. The Earth's atmosphere acts as a prism and splits out the colors of the sun, revealing a flash of green and more rarely blue or violet.

When atmospheric thermal inversions are present, conditions are right for each inversion layer to act as a prism. Thermal inversion layers make their mark by distorting the shape of the setting sun. A green flash can appear at the top of the sun as the light of the setting sun passes through each thermal inversion layer. Several Green Flashes can appear during a single sunset when inversion layers are present. Each flash lasting just a second or two.  This "Green Flash" at the top of the sun was photographed from a hill overlooking Pacific Beach, California on Christmas Eve, December 24th, 2007. The horizon line is the Pacific Ocean.
