Explanation: This was one strange sunset. For one thing, the typically round Sun appeared distorted, geometrically, and multiply layered. For another, some of these layers appeared unusually green. The Sun, of course, was just fine -- its odd appearance was caused entirely by its light refracting in the Earth's atmosphere. When layers of the Earth's atmosphere are unusually warm, layers of the Sun may appear distorted or even seen multiple times. The effect is most strong nearest sunrise and sunset when terrestrial inversion layers occupy distinct altitudes above the horizon. Different colors of the Sun may also become deflected by significantly different amounts, so that the uppermost superior image may appear momentarily green -- a phenomenon known as a green flash. The featured image was taken in February from Porto Venere, Italy, with San Pietro church situated in the foreground.

THE GREEN FLASH......has any of my Navy buddies see it???
And here I thought a green flash was caused by too much copper in the upper atmosphere...
I suspect that it is an optical illusion, like the one you get if you stare at a white spot for a little while, then look away, and see a negative black spot. The last bit of the sun is red at sunset and when that disappears, you can sometimes see a color-negative green flash.
This is actually a very very rare event to capture on film- I’ve seen a few such photos- it only occurs when conditions are just right, and it happens in an instant, making it very hard to capture or even predict
How to See the Green Flash
The “Green Flash”, also known as the “Green Ray”, is a visual phenomenon that occurs at sunset. It is considered good luck in some cultures to see the green flash; others see it as a more foreboding omen. Whatever your view, it is a brief but memorable sight but you have to be quite lucky to see it. Follow the steps outlined here to increase your chances

It is not an afterimage illusion. It is refraction.
It is green within the separated portion at the top. Maybe you need to adjust the color balance on your monitor. Older people tend to set their monitors toward the blue to compensate for yellowing by their crystalline lens in the eye.
Many times, my working on the bridge put me in the position of watching sunsets more than most.
