The green flash at sunset is a real, rare optical phenomenon where the sun's top rim briefly flashes green for a second or two just as it disappears below the horizon, caused by Earth's atmosphere acting like a prism, separating sunlight into colors and scattering blue/violet, leaving green visible against a clear horizon, often enhanced by mirages.
As the Sun gets closer to the horizon, the green rim becomes fainter due to atmospheric reddening. According to the above, it is probably correct to conclude that although a green rim is present during every sunset, a green flash is rarer because of the required mirage.
The green flash is a phenomenon that occurs at sunset and sunrise when conditions are favorable, and results when two optical phenomena combine: a mirage and the dispersion of sunlight. As the sun dips below the horizon the light is being dispersed through the earth's atmosphere like a prism.
It is most visible just as the sun dips below the horizon as seen from a few yards above sea level. This green flash usually lasts about two to three seconds. The inferior mirage, as seen over asphalt on a hot summer day (hot air below cooler air), is the responsible culprit.
What time of year is best for seeing green flashes?
The month of October is often a great time to see the green flash at sunset. It is said that to see a green flash will bring you good luck. So I hope that if you on the Mendonoma coast, you will take the time to watch the sunset. A green flash sometimes appears at the moment the sun is disappearing from view.
If there is a green in Paradise, it cannot be but of this shade, which most surely is the true green of Hope.” In layman's terms, the green flash is an optical illusion that occurs from the refraction of sunlight in the atmosphere.
The brief flash of green light is seen more often at sunset than at sunrise. When the conditions are right, a distinct green spot is briefly visible above the upper rim of the Sun's disk; the green appearance usually lasts for no more than two seconds.
The 30 minutes before sunset (and after sunrise) is called Civil Twilight, the brightest phase of twilight, when there's enough natural light for outdoor activities and the horizon is visible, though photographers also call this time the Golden Hour for its warm, soft light.
What is the rarest sunset color? The rarest type of sunset is one with violet or indigo colors. To understand why thought, you have to know a little bit about the science of sunsets.
Can you explain the green flash of light at sunset at Key West?
When the conditions are right, a green spot is visible above the upper rim of the sun's disk. Green flashes occur because the atmosphere can cause the light from the sun to separate out into different colors. Locals know of the green flash and make a point of looking for it every night.
(WSAV) – Spring is here, and as summer approaches, the sunrise and sunset become popular subjects. During these events, one can witness an optical phenomenon known as the green flash. The green flash is a brief occurrence visible just after sunset or before sunrise.
The green flash is an optical phenomenon that you can see shortly after sunset or before sunrise. It happens when the sun is almost entirely below the horizon, with the upper edge still visible. For a second or two, that upper rim of the sun will appear green in color (or sometimes blue).
Not to be confused with the fictional superhero, the “Green Flash,” the solar “green flash” is a natural phenomenon that is just as elusive. For centuries, mariners have shared numerous ominous stories about these magical bursts of green light directly above the Sun as they watched it set on the water.
It's a real—and rare—phenomenon that happens just as the sun dips below the horizon. 🌞 What you're seeing is sunlight bending through the atmosphere, separating into colors like a prism. For just a moment, a burst of green light appears. And yes, we caught it—right next to a sailboat off Key West!
The Greek Island of Santorini must have one of the most famous sunsets in the world and the evening light at Oia is very beautiful… although crowded with tourists.
What many people don't know is that there are four kinds of twilight: sunrise or sunset, civil twilight, nautical twilight, and astronomical twilight. In this article, we are going to talk about these four kinds of twilight in detail.
While on Earth, blue suns, moons, and sunsets are a rare occurrence, blue sunsets appear to be the norm on Mars. The photograph of the sunset on Mars taken from the Gusev crater by the Mars Exploration Rover Spirit (Fig. 1 ) shows a blue Martian sunset.

The reverse sunset, also known as “reverse twilight” or “anti-sunset”, is a fascinating atmospheric phenomenon. During a reverse sunset, the sky opposite to where the sun is setting becomes infused with warm hues of orange, pink and purple.
The golden hour is also sometimes called the magic hour, especially by cinematographers and photographers. During these times, the brightness of the sky matches the brightness of streetlights, signs, car headlights and lit windows.
While this usually causes the sky to appear red at sunset, a rare blue flash occurs when conditions are very clear, allowing the highly refracted blue light to momentarily be visible just before the sun disappears entirely.
