Answer 2

The circles around the sun are called sun halos or 22-degree halos. These optical phenomena occur when sunlight is refracted by ice crystals in the atmosphere, creating a ring of light around the sun. The halo appears at an angle of approximately 22 degrees from the sun, hence the name "22-degree halo".

Sun halos are often circular in shape and can be seen during certain weather conditions, such as when there are high, thin clouds or ice crystals in the atmosphere. The ice crystals act as prisms, bending the sunlight and creating the halo effect. The size and brightness of the halo can vary depending on the size and shape of the ice crystals, as well as the angle of the sunlight.

It's important to note that sun halos are different from rainbows, which are caused by the refraction and reflection of sunlight through water droplets in the air. Sun halos are typically larger and have a circular shape, while rainbows are semi-circular and appear opposite the sun.

So, the circles around the sun are known as sun halos or 22-degree halos, and they are caused by the refraction of sunlight by ice crystals in the atmosphere
