Phenomenon called the "green flash"

Thats pretty awesome

It happens fast, but you can see it in the last couple frames of the video: the air turns green because the sun sets over the horizon but it is still shining up through the ocean.

I have only seen it one time irl. It was awesome.

What the hell?! I jumped a little. That was really cool.

i cannot be certain, but i think this clip is off The Pirates of the Caribbean, At World's End
