Have you ever seen the Green Flash?

The green flash is a phenomenon that occurs at sunset and sunrise when conditions are favorable, and results when two optical phenomena combine: a mirage and the dispersion of sunlight. As the sun dips below the horizon the light is being dispersed through the earth’s atmosphere like a prism. As the light passes through the familiar Roy G. Biv of the spectrum, sometimes a flash of green can be seen for a few seconds.
