Q. Recently, a rare celestial phenomenon called a "double sun halo" was recently witnessed in which region of India?
Answer:
Ladakh
Notes: Recently, a rare "double sun halo" was observed over Ladakh. This optical phenomenon features two concentric rings around the sun, caused by sunlight refracting through ice crystals in cirrus clouds. The inner halo has a 22-degree radius, while the outer halo spans 46 degrees. The unique alignment of hexagonal ice crystals in the clouds creates this dazzling effect, making it an uncommon sight, especially in ideal conditions like those in Ladakh.
