There are two quotations from Sun Yijing in the sky.

The appearance of two suns is generally called a magic day. It will rain 48 hours after the illusion, but there are exceptions.

Magic day. In the translucent thin cloud in the sky, when there are many ice crystals near sunrise or sunset, three beams of light emitted by icicles enter people's eyes, and the middle beam directly comes from the middle sun, which is the real sun; Next to the two rays, the sunlight is refracted by a hexagonal crystal column. In this way, in people's eyes, there are two other suns on both sides of the real sun in the middle, which are actually virtual images of the sun.

Magic sun usually appears at the same time as solar halo, which surrounds the sun in a ring shape and is colored. The appearance of solar halo often indicates that the weather will change to some extent. As the saying goes, the sun is dizzy in the middle of the night, the rain is dizzy in the month, and the wind is dizzy at noon. So if there is a precursor, it will rain.
