Huge sun halo appears in the Beijing


26th June 2022 – (Beijing) A huge sun halo appeared in the Beijing yesterday attracting citizens to take pictures. After netizens posted photos of the sun halo on the Internet, it immediately caused a heated discussion.

Halos around the sun and moon are certainly not rare. They are caused by high cirrus clouds refracting light. Cirrus clouds are so high in the sky (typically higher than 20,000 feet), they are made up of millions upon millions of tiny ice crystals which readily refract the light from the sun or moon.
