radioweather writes "The heart of the sun came alive the evening of Valentines day. 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 about 2 days as the slower Coronal Mass Ejection (CME) hits earth. This will be a test of how well our newest technology handles stray energy from such solar disruptions."
