The Sun's Halo was spotted again on Wednesday in parts of Hyderabad, days after people living in India's tech hub witnessed a rare phenomenon in skies over Bengaluru. The optical phenomenon is a result of ice crystals present in the atmosphere that appears covering the sun when refracted by sunlight. How Sun halo is formedClouds contain millions of ice crystals which refract, split, and even reflect the light to give an impression of a circular rainbow ring. Sunlight through the ice crystals causes the light to split, or be refracted. During the process, light undergoes two different refractions once when it passes through ice crystals and the second when it exists.
