Sun's Intensity Sparks Up Powerful Flares

The Sun has been unleashing strong solar flares this week and more can be expected in the coming days.

Four were spotted this week, marking the most intense activity yet this year and causing limited interruptions to high-frequency radio communications.

One of them was classified as an X3.2 flare, with X-class flares being the most intense type, US space agency Nasa said.
