A brilliant halo was found around the moon on Wednesday evening in the sky across the State, including in the capital city here.
An astronomer said the unusual sight is caused by cirrus clouds that are around 20,000 feet or higher above us. They are made of tiny 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.
