In Search of the Green Flash

Sunset watching is a popular activity here, typically enjoyed with a glass of rum in hand. The other night, someone at the beach bar mentioned the green flash and I was asked for an explanation of this rare phenomenon.

I have met two people who claim to have seen it, a brilliant green flash of light at the last moment of sunset, caused by a refraction of the sun's rays. It is said to occur only when atmospheric conditions are right and you are lucky to see it even once in your lifetime. For some individuals experiencing the green flash is an item on their life list and for others merely an excellent excuse for spending their evenings by the beach, drinking rum.
