Solar Flare 2011

A powerful solar flare that caused a great geomagnetic storm has disrupted communications by radio and could disrupt power grids, radio and satellite communication, while in the next few days, NASA said. A powerful wave of charged particles in the plasma of the sunspot the size of Jupiter, the most effective known mainly in 4 years, has already changed the radio in southern China. The flash X-class - the largest of these categories - erupted in 0156 GMT on Tuesday on the basis of the U.S. space agency. Geomagnetic storms usually last 24 to 48 hours - but some may last days, through a statement from the U.S. National Weather Service.NASA Solar Dynamics Observatory said he noticed a large coronal mass ejection (CME) associated with the flash blasting towards the Earth about 560 miles per second (900 km / sec). Flare spreads Lively 1158 under the sun in the southern hemisphere, which had hitherto remained in the northern hemisphere after the flash operation. E 'was followed by several smaller rockets up days.
