Is the sun a rainbow on the outside and on the inside?

This is called a solar halo. The first time I saw it, I was also terrified, thinking that there was an alien invasion. Later, I found out that it was called a sun halo. With this thing, you know that there may be a strong wind the next day.

A circle of rainbows around the sun is a halo phenomenon. The phenomenon of solar halo is the same as the lunar halo seen around the moon at night, except that the solar halo appears around the sun, which is formed when sunlight hits tiny ice crystals in the upper atmosphere. At miles above the Earth, air temperatures can easily drop below the freezing point where ice crystals can form, and the sunlight or moonlight that passes through the ice crystals is refracted back, forming a solar or lunar halo around the sun or moon.

When light hits the ice crystals in the cirrostratus clouds, it is refracted twice and dispersed into various colors of light in different directions. When there are cirrostratus clouds, there are countless ice crystals floating in the sky, and the ice crystals in the same circle around the sun can refract the same color of light into our eyes to form an inner infrared violet halo. The halo is usually ring-shaped or arc-shaped, and has seven colors: red, orange, yellow, green, blue, indigo, and violet.

The reflection of ice crystals from the sun to the human eye is called a solar halo. Ice crystals in the atmosphere are usually brought by cirrus clouds, and when sunlight hits the ice crystals, they are reflected off the human eye, creating rings or arc-shaped coils, usually red on the inner and violet on the outside.

It is a solar halo, indicating that it may rain late at night.

A rainbow that circles around the sun is often referred to as a halo or halo. They are optical phenomena produced by the reflection and refraction of light rays in water droplets or ice crystals, which can be seen in the sky under specific weather conditions. Halos usually have some characteristics like the shape of the ring, color bands, brightness, etc.

These features are caused by the different reflections and refractions of light that occur in ice crystals or water droplets.

Halos can also be further classified based on their color and shape. For example, in a circular halo, the inner circle is often blue and purple, gradually changing to green and yellow outward, with the outermost ring being red. This halo is known as a variegated halo.

When the sun is below the horizon, the bands of light that form are called horizon halos or horizon bands.

In conclusion, the rainbow that circles the sun is often referred to as halos or halos, and they are a beautiful and peculiar natural phenomenon. During the observation process, it is necessary to pay attention to the protection of the eyes to avoid optical damage caused by looking directly at the sun. It is also important to observe the weather conditions in order to better observe and experience this natural wonder.
