Who saw the solar halo on 5.20?

Solar halo is a light phenomenon formed by refraction when sunlight passes through ice crystals in clouds, 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.

"Dizziness" mostly occurs in spring and summer. There is a folk proverb called "the sun is dizzy in the middle of the night and the moon is dizzy at noon", which means that if there is a solar halo, it will rain in the middle of the night, and if there is a lunar halo, it will be windy at noon the next day. Solar halo can be a precursor of weather change to a certain extent, and it may turn cloudy or rain when it appears. But there is no scientific basis to say that this phenomenon can predict the drought and flood of this year's climate.

This has nothing to do with the earthquake.
