Sunspot as big as Earth visible without use of telescope

A Sunspot, identified as Sunspot 3363, has been spotted on the surface of the Sun. It is currently visible without the help of telescopes, according to Souda Atul Bhat, co-ordinator, Poornaprajna Amateur Astronomers’ Club, Udupi.

A Sunspot is a region on the surface of the Sun where the temperature is less than its surroundings. “The surface of the Sun is as hot as 5,000 degrees, while these regions are at 4,500 degrees. This reduction in 500 K between the region and its surroundings, which means the surroundings of the Sunspot give out more light than the Sunspot and thus, it appears dark,” he said in a release issued on Thursday.

“The Sunspot 3363 has been visible since July 6, 2023, and might be visible until the end of this week, before it moves away from our view and not appear again,” said Mr. Bhat, who is assistant professor of physics at Poornaprajna College in Udupi.
