The sun awakens again as An intense solar flare took out low-frequency radio communications over South America and the Atlantic Ocean earlier today (Sept. 28), and the unstable sunspot is likely to erupt again. NASA’s Solar Dynamics Observatory spacecraft captured an amazing video of the solar flare from space. At 10:53 a.m. EDT (1453 GMT), the medium-size M7-class solar flareburst from the sunspot called Active Region 2422 (AR2422).
The explosion unleashed extreme ultraviolet radiation that rushed over the Earth, officials at the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center said in a statement. The peak of the action, when there was a brief radio communications blackout on the sunlit side of Earth, was about 5 minutes later, at 10:58 a.m. EDT (1458 GMT). The flare ended 7 minutes after that. FULL REPORT
