The 'green flash' is a phenomenon of sunset at sea in particular atmospheric conditions. Under some set of conditions (mainly really, really clear air, I think...) then just as the very last little bit of the sun disappears over the horizon at sunset there is sometimes a very bright and very brilliant bright emerald green flash of light.

It only lasts for a few seconds. But it often takes years at sea to finally see it. But it is there.

Wow. That sounds very cool. Guess since I'm not in the position to spend lots of time at sea this is something outside my realm... but, VEY cool to hear about. :-)

Yeah, if you are watching the sun go down, just before it actually goes below the horizon, the sun itself actually turns bright green, it's vey cool.

On clear days, yes, and when the sky is turning pink instead of orange.
