Bhubaneswar: A brilliant celestial display was observed in Bhubaneswar and other parts of Odisha when a halo was found around the moon today evening.
An astronomer said this unusual sight is caused by cirrus clouds that are around 20,000 feet or higher above us. They are made of tiny and ice crystals. Moonlight or sunlight through the ice crystal causes the light to split, or be refracted. When at just the right angle, it causes us to see the halo.
Weather folklore says a ring around the sun or moon means it will rain soon. While that is not always the case, it often is actually true. Cirrus clouds typically move into an area well ahead of a storm system that may cause rain in the next day or so.
Usually halos around sunlight have been observed across the world on different occasions.
