A garland of lights in the sky suddenly turns. Lights begin to flicker and after a few seconds left. The entire country remains in darkness. The situation is repeated all over the world. A year later the situation has not changed. Million deaths are registered, and our civilization is almost over. Case, a solar storm.

It pulled like a description of Hollywood's apocalyptic film, but unfortunately could not be fictional, write Friday newspaper ABC.
Part of the report published two years ago by the U.S. National Academy of Sciences (NAS) funded by NASA. Study warns of huge bundles of plasma from the sun to reach our planet in 2012 or 2013, when the king planet will reach its peak activity as part of the solar cycle of eleven years. It's hard to happen, but there is a real possibility.
The current dependence of electronic and satellite communications requires a large space storm cause 20 times more economic damage than Hurricane Katrina. If something similar were to happen, we have a chance? Researchers at the University of Bardford believe it, provided it be not taken by surprise and be alerted to take action early. In this respect it is working on developing a major new system to predict solar movements.
Involves the release of huge solar storms amounts of hot gas and magnetic forces in space at a speed of 1,600,000 miles per hour. Although major solar eruption usually late to arrive on Earth, the catastrophe could precipitate, given that one of the largest, most recorded in 1859, reached the planet in just 18 hours (called "Carrington Event", the British astronomer who measured and which caused a collapse in most networks worldwide telegraphy). Solar Lightning caused so much damage that could not only take a few minutes.
Until now, solar weather predictions were not made by hand. Experts seek satellite images of the sun in two dimensions and evaluates the likelihood of future activities. But the team at Visual Computing Center of the University of Bradford, United Kingdom, developed the first automated system accessible to the prediction using 3D images generated by NASA satellites and the European Space Agency (ESA) Solar and Heliospheric Observatory (SOHO).
Bradford automated prediction system of solar activity, called ASAP, in English, "As soon as possible", already used by NASA and ESA, identify and classify sunspots. The system is able to accurately predict a solar storm six hours before and the team working to achieve a similar prediction for future large solar eruptions.
"Solar weather prediction is still in its infancy, probably where the weather forecasts were 50 years ago. However, our system is a big step forward," explained Professor Rami Qahwaji, who leads the research. According to him, "creating an automated system can work in real time, opening the possibility of more rapid predictions.
On the other hand, scientists believe that the new satellite of NASA's Solar Dynamic Observatory (SDO), which came into operation in May, will follow in detail and will enhance the ability of solar activity prediction.
