radioweather writes "For the first time since solar cycle 24 began, the sun produced a massive X-class solar flare, the strongest type of flare event. This comes from sunspot group 1158, which produced an M-class solar flare on Sunday. The EVE X-ray imager on the solar dynamics observatory shows a bright explosion on the sun, so bright it made a lens flare. The last X-class solar flare was on December 13th, 2006 and was part of solar cycle 23. Look for spectacular auroras in a couple days as the slower Coronal Mass Ejection hits earth. This will be a test of how well our newest technology handles stray energy from such solar disruptions."
