Explanation: Yes, but can your green flash do this? A green flash at sunset is a rare event that many Sun watchers pride themselves on having seen. Once thought to be a myth, a green flash is now understood to occur when the Earth's atmosphere acts like both a prism and a lens. Different atmospheric layers create altitude-variable refraction that takes light from the top of the Sun and disperses its colors, creates two images, and magnifies it in just the right way to make a thin sliver appear green just before it disappears. Pictured, though, is an even more unusual sunset. From the high-altitude Cerro Tololo Inter-American Observatory in Chile one day last April, the Sun was captured setting beyond an atmosphere with multiple distinct thermal layers, creating several mock images of the Sun. This time and from this location, many of those layers produced a green flash simultaneously. Just seconds after this multiple-green-flash event was caught by two well-surprised astrophotographers, the Sun set below the clouds.

Seen the green sunset flash on the ocean several times... A very quick but awesome sight.

I live in the tropics and have been able to see unobstructed sunsets (clouds aside) over the ocean for 13 years. Yet to see a real flash.

Also saw it several times at sea. Always after a heavy storm had cleaned all the scum & dust out of the air.

The green flash is real??? I grew up looking for it across the Pacific whenever I was outside at sunset. I decided that it was a myth.

Never seen it myself so I cannot vouch for it.

When I was young and working the longleg commercial fishing boats in he Gulf the Green Flash was talked about but was regarded by most as some sort of seamen’s myth. I kind of thought that too until I saw it. I just happened to be looking toward the setting sun and Damn! its REAL! I have seen it from the beach twice since then and once more at sea. Getting a photo of it is hard unless you have a digital movie camera, I guess. It is too quick.

I always heard that the air had to be absolutely clear and cloudless to the west and it was that the times I saw it. This pic has clouds. I was on the gulf at the Campeche banks the first time.

Do you know if a green SUNRISE flash is possible?

I’ve never heard of the green flash.

I’ll keep an eye out now.
