Sun unleashes four potent solar flaresWashington (AFP) May 15, 2013 The Sun has unleashed four potent solar flares 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, the US space agency said. "This is the strongest X-class flare of 2013 so far, surpassing in strength the two X-class flares that occurred earlier in the 24-hour period," NASA said of the flare that peaked at 0111 GMT Tuesday. ... read more |
