The phenomenon popularly known as the 22 degree circular halo of the sun or also called a moon ring or winter halo, occurs when the sun’s or moon’s rays get deflected or refracted through the hexagonal ice crystals present in cirrus clouds, a senior researcher with the MP Birla Planetarium told Press
