A new giant solar explosion, much stronger than that recorded by NASA devices in November, was discovered on December 6, the satellite Solar Dynamics Observatory (SDO), the U.S. space agency launched in February, inform popsci.com, quoted by Mediafax. The new eruption occurred in the southern hemisphere of the Sun and solar filament material ejected into space covers an area of over 700,000 km, equivalent to twice the distance between Earth and Moon. However, the ejection of solar plasma was 96,000 km longer than that recorded during the previous solar flare that occurred in November.

According to Popular Science magazine's electronic edition (popsci.com), the flow of solar plasma is not going to Earth, and for this reason that experts say is not likely to affect the explosion Monday solar orbit satellites and electronic or electrical devices the Earth's surface. This information was confirmed by spaceweather.com site. However, carrying solar wind particles expelled by the Sun, went on the night of Tuesday to Wednesday, above the polar regions of Earth, "lightly touches the" Earth's magnetic field and generating spectacular aurora borealis above Sweden, near the Polar Circle.
According to the site spaceweather.com, a new "wave" of solar wind is moving towards Earth and will reach close to our planet on 10 December. Astronomy enthusiasts at high latitudes will be able to admire the aurora borealis over the weekend in November.
To protect the electricity distribution networks from the ground, NASA designed Space Solar Shield project, which will be inaugurated soon. Solar Shield will use the data from the Solar and Heliospheric Observatory (SOHO) satellite system and stereo to launch a warning signal from the ground through which specialists will be able to stop at a distance, using computers, electrical generators The high voltage network line, thereby preventing them from damaging solar storms.
Following high-intensity solar flares, the shock wave can damage satellites, electricity distribution networks and communication lines across the globe.
According to international media, some experts believe that the Earth will be hit by unprecedented levels of magnetic energy due to solar flares, circa 2013.
During a solar eruption, a huge amount of energy that the Sun is in the chromosphere and the crown is issued instantly. Matter is designed to very high speed in interplanetary space. The phenomenon is accompanied by the emission of X-rays, radio waves and, if more powerful eruptions, visible light. When they get close to Earth and enters the atmosphere, especially over the north pole region, the particles create polar auroras. They also disrupt the propagation of radio waves around the globe, affecting the electricity distribution networks.
Phenomena varies with frequency and intensity for almost 11 years, this time recording a number of sunspot minimum and maximum. Solar activity is influenced by Sun's rotation and magnetism.
