Second Biggest Solar Flare of the Solar Cycle Hits Earth
The Sun erupted with one of the largest solar flares of this solar cycle on March 6th, 2012. Such a coronal mass ejection (CME) could result in a 
severe geomagnetic storm, causing havoc to high frequency radio communication, GPS systems, and power grids. Check out the updates on the NASA website. Cool video of the actual coronal mass ejection too.
