Hey that is a nice looking photo. Where in FL is that. I have vistited FL a few times and they do have great sunsets. I also like watching the sunset in Santa Cruz, CA on a perfect day over the ocean though. Makes for great long walks on the beach!![]()
The green flash?
Thanks for your post!
We are visiting relatives in Bradenton.
dude didn't you watch piartes of the caribean 3 it all there just rent the movie.
The movie is BS.
There really is a green flash; I've seen it.
The last instant the sun goes below a very distant horizon appears distinctly green. It's due to chromatic refraction within quite a lot of atmosphere. Green is bent less than yellow/orange, so there is an instant where yellow/orange is invisible, but green isn't. There is also blue and violet, but the eye isn't nearly as good at picking those colors out, so it appears green.
There is presumably a similar effect right at sunrise, but it's hard to know exactly where and when to look.
It's next to impossible for east coasters to see the effect, except perhaps from southwest Florida. You need a very distant, unobstructed western horizon. Even distant trees can spoil it. A calm ocean is just about the only way.
