Why do corals appear around the Sun and Moon?

What is the sun halo
In fact, the big light around the Sun is not a circular rainbow. It is merely the result of a common optical phenomenon in nature: light refraction.
Specifically, this halo is called "Sun halo". During the day, the sun shines through cirrus clouds (Cirrostratus) at an altitude of 6-8 km. Because this cloud has a crystal structure, the refracted light makes the halo appear with the same color as the rainbow we often see.
Sun halo.
The halo around the Sun is not only silver, but sometimes there are many iridescent colors like rainbow colors; most of the Moon's halo is silver, this light in meteorology is called halo (halo, Sun halo).
The creation of halo is due to the effect of the atmosphere . At these times, areas near the Sun or Moon often appear hot air and cold air interspersed with each other. Hot air filled with steam rose above the cold air and flew up into the sky. When the steam in the sky encounters low temperature condensed into hexagonal prismatic ice particles, the Sun or Moon light will shine on these ice particles and produce refraction, thus we will see the halo around the Sun or the Moon. When the Sun or the Moon appears halo, it is expected that the coming days will be rainy or windy days.
