Has anyone ever seen the green flash?
This question came up in another discussion, so I thought I'd throw it out here for general discussion. It's just been a source of fascination for me ever since I heard about it.
Here's the description from wikipedia:
Green flashes and green rays are optical phenomena that occur shortly after sunset or before sunrise, when a green spot is visible, usually for no more than a second or two, above the sun, or it may resemble a green ray shooting up from the sunset point. Green flashes are a group of phenomena stemming from different causes, and some are more common than others.[1] Green flashes may be observed from any altitude (even from an aircraft). They usually are seen at an unobstructed horizon, such as over the ocean, but are possible over cloud tops and mountain tops as well.

It's supposed to be a pretty rare phenomenon, more likely to be observed over the ocean, but since the definition mentions mountains as well, just thought I'd ask.
