Is there a halo on the moon sunny or cloudy?

Halo (light wheel, ice bow, glory) is an optical phenomenon in nature. It is a color aperture formed by the refraction of ice crystals when the light of the sun or the moon passes through high and thin white clouds (cirrus, cirrostratus or cirrocumulus), and the color arrangement order is in infrared violet. The aperture around the sun is called solar halo, and the aperture around the moon is called lunar halo.

The appearance of solar halo or lunar halo often indicates that the weather will change to a certain extent. Generally, a solar halo means it may rain, and a lunar halo means it will be windy. Sometimes there is a gap in the lunar halo, and the direction of the gap is the direction of the wind. Therefore, there is a folk proverb: "It rains at night when the sun is dizzy, and it is windy at noon when the moon is dizzy" and "It rains when the moon is dizzy".
