    A Sun Halo is an optical phenomenon, formed when the Sun or Moon align with ice crystals in the sky, causing the light to split. The rare sighting happens just when the two are at the exact right position.

    People in the coastal Indian town of Rameswaram were gobsmacked to witness a spectacular rainbow ring around the Sun on Monday. The rare sighting lasted for at least thirty minutes.

    People have shared pictures and videos on Twitter of the rare spectacle, expressing feelings of hope for better days amid the COVID-19 gloom. The pictures and videos have sine gone viral on social media. 

    ​Weather experts say a ring around the Sun or Moon could be a sign of rain in the region. The claim, however, is not 100 percent accurate. The unusual sight is caused by cirrus clouds. These cirrus clouds generally navigate into the area ahead of a storm.
