NASA SDO - X5.4-class Solar Flare, March 7, 2012

Right at midnight UT time the active region 1429 unleashed a powerful X5.4-class solar flare. X-class flares are the strongest of the flares. They are major events that can trigger planet-wide radio blackouts and long-lasting radiation storms. It appears that right after the large X5.4 flare another slightly lower, X1 flare (5 times smaller) occurred. You can clearly see a wave going across the Sun. We are still gathering data and the Space Weather Forecast Lab will be having updates available soon. Credit: NASA SDO
