The spectacle of "big eyes" appeared in the sky.

The sun is surrounded by a mysterious halo, staring at the world from the sky like a huge "eye".

In fact, this astronomical phenomenon is called magic sun, which is formed by hexagonal ice crystals in cirrus clouds in the sky refracting sunlight. Cirrus is a kind of high-altitude cloud, which is the highest cloud in the troposphere and consists of tiny ice crystals at high altitude. Usually, when the magic day appears, part of the sun will be blocked by cirrus clouds. The magic day usually appears when the sun angle is low, and this astronomical phenomenon will not appear at noon. Magic days are often called "solar halos" or "holidays".

This wonderful landscape made everyone on the beach stop to look up and was successfully captured by photographer Robert. "It was a fine day, and I went to the beach with some friends," Robert recalled. "At about 1 in the afternoon, I looked up at the sky, and at that moment I saw the halo around the sun. Aura is rare and often incomplete. Many people on the beach want to photograph the halo with their mobile phones, but it is not easy. I took this photo with an ultraviolet filter and a professional camera. That's really spectacular. "

Wilder, a local weatherman, explained, "The sun shines on ice crystals and a magical day is created. The main influencing factors include the direction and number of ice crystals and the number of cirrus clouds. These ice crystals act like prisms, bending sunlight and forming a halo around the sun. The shape of the halo is determined by the height of the sun. "

People usually think that this magical day is an auspicious sign. During the Battle of the Roses 146 1 period, Earl Edward, the eldest son of York family in England, who later became Edward IV of England of England, saw this spectacle, and then he encouraged the army to say that it was a good omen and finally won.
