Why are there three suns in Quanzhou, the magical sun and the rare wonders of the sky?

We all know that there is only one sun in the world, and only one sun can make everything grow naturally. On June 1 65438+1October1day, three suns were found in the sky. Why are there three suns? Then let's use constellation knowledge to reveal the specific reasons!

There are rare magic days and astronomical wonders in Quanzhou.

165438+1On the afternoon of October 2, some Quanzhou citizens were surprised to find that there was a true and false sun in the local sky. Chen Huabiao, executive director of Fujian Astronomical Society and teacher of Quanzhou No.1 Middle School, said that the "sun" on the left and right sides of the real sun is actually a virtual image of the sun. He said that this is a rare "magical day" spectacle.

Why are the wonders of "magic days" rare? Chen Huabiao dispels doubts: "The conditions for the formation of magic wonders are very harsh, and it takes cold weather to appear clouds containing ice crystals in the sky. Such clouds rarely appear in low latitudes such as Quanzhou, but are more common in high latitudes and cold regions."

Yesterday 16:30, Mr. Chen photographed the "magic sun" in the ancient city. The big dot on the left is the sun, and the small seven-color dot on the right is the magical sun. According to reports, due to the influence of irregular clouds yesterday, the magic day on the right side of the sun was more obvious, and the magic day on the left side of the sun was darker. These two virtual images of the sun do not appear at the same time, so it is impossible to "be in the same frame".

It is understood that no one in Quanzhou has photographed the "magic day" before, and this time it is really rare.

Why are there three suns?

This phenomenon that three suns appear at the same time is called a holiday. Because this phenomenon is relatively rare and ancient science is underdeveloped, people often regard it as a sign of disaster. In fact, the simultaneous appearance of "three suns" is an optical phenomenon and a special solar halo.

In the polar regions, in the cold and clean sky, a series of holidays can often appear on the halo around the sun, which is very spectacular. This phenomenon is also called magic day. The causes of magic sun phenomenon 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.
