The green flash is an optical phenomena consisting of a green coloration often in the form a flash of short duration (no more than 2 seconds usually) that occurs shortly after sunset or just before sunrise.



The explanation lies once again in refraction: light moves more slowly in the lower air, due to its higher density, so the sunlight follows paths that curve slightly in the same direction that the Earth is curved. Higher frequency light (green) curves more than lower frequency (red/orange) so green remains visible from the upper limb of the setting sun while the red and orange rays are obstructed by the curvature of the earth.

Wow, nice work! I've looked and looked as well, never seen it though...

Was it apparent to the naked eye as well as the photo?

Great shot Toad, probably never capture it like that again.
