Sun wakes up, spews X-flare toward Earth The sun has been silent for a while but has awakened with a vengeance as reports have indicated that the sun’s first X-flare of the year capable of damaging electrical grids and unguarded electronics – erupted Wednesday in the direction of Earth, and its full impact is yet to be felt. NASA says The flare, observed by NASA’s Solar Dynamics Observatory satellite, contains the energy of millions of hydrogen bombs exploding all at once.   The sun is at its solar storm maximum, but solar flare activity on its surface has been unusually quiet. However, a direct hit from an X-flare, the most powerful category, can have a major impact on communications, electrical grid systems and other unprotected electronics and automated control systems that run life-sustaining critical infrastructures.
