Last night we rode the bikes 2 miles to get the 100 yards across the street to our favorite sunset place. The parks people made it easy and put a gate in that we could have used, but we love the ride. It's quite a phenomena. All we tourists stop whatever we're doing for 15 minutes and rush to a spot to see the sun go down. I think it irritates the locals just a bit.
That sunset was unique, as they all are, I suppose. When the horizon is clear and the spot where the sun apparently disappears is over water, there's a refraction that takes place. It spreads the spectrum out a little and causes color shifiting. That and absorption cause the shading you see in a sunset picture with the dark, blood red at the bottom.
Just as the last bit of the Sun slides over the horizon, there's the opportunity for a green flash of light. It's very fast like the glint of a diamond and fiercely green. I've heard that on rare occasions it flashes upward to the base of clouds and makes a very fast green hue line running to the horizon. Never seen that one, but yesterday I saw my second green flash.
Sorry, No pictures of the flash.
