The largest solar flare in the last 4 years!
LONDON - A powerful solar flare triggered a huge electrical storm, which has already disrupted radio communications in China could disrupt communications and electrical, radio and satellite in the coming hours. Astronomers from around the world are following with great attention to the phenomenon, the most powerful seen in the last four years, which has already been suspended on shortwave radio communications in China.
THE STORM - The explosion on the surface of the sun occurred at 2:56 Tuesday morning, according to NASA and caused distortions in the Earth's ionosphere over China. Geomagnetic storms usually last 24-48 hours, but some last longer. The solar flares are violent explosions in the photosphere of the sun, the equivalent of millions of hydrogen bombs together, caused by strong magnetic activity and emitting large amounts of radiation, perhaps by investing the Earth. According to experts, could vary the ground-air-, sea-land, short-wave transmissions and those of amateur radio. Also according to the experts the sun is awakening from the point of view of the flare after a period of low activity lasted several years, and this could be the first in a series of eruptions.
