What is the green flash of Florida keys?

The green flash is a rare optical phenomenon that occurs briefly at sunrise or sunset when the upper edge of the sun's disk briefly appears green. It is caused by atmospheric dispersion, which separates the colors of light as they pass through the atmosphere. The green flash is most common in the tropics and subtropics, and is said to be best seen from the Florida Keys.

To see the green flash, you need to be in a location with a clear horizon, and you need to be looking directly at the sun as it rises or sets. The flash typically lasts for only a few seconds, and it can be difficult to see if you don't know what you're looking for.

The green flash is a beautiful and fascinating phenomenon, and it's definitely worth trying to see if you're ever in the right place at the right time.
