Solar flare particles dispersed covering almost half of the solar surface
Equipment of the U.S. space agency reported early on Friday (7) a large solar flare activity that could disrupt satellites, power grids and telecommunications from Wednesday (8).
A large cloud of particles increased rapidly and dispersed looking cover an area nearly the size of half of the solar surface. According to the weather service in the United States (NWS, its acronym in English), not seen since 2006 a solar storm of this size.
Solar flares occur early in the event as a small flash of light. A dark material, the filament eruption is issued and extends over a wide area of the solar surface. The rarity of this solar flare is just the size expansion.
The Solar Dynamics Observatory (SDO), NASA observed the peak of solar activity at 2:41 a.m. (Eastern Time), the images were captured great detail. The team classified the SDO solar explosion as a "visual spectacle. " The particles resulting from the explosion, moving through space at 1400 km / s. According to a statement from the NWS, the phenomenon can cause a magnetic storm of small to moderate, from 15h GMT. It can cause problems on GPS systems, forcing planes to alter their routes to fly over polar regions.
The explosions on the surface of the sun have caused concern among scientists. The star has cycles of activity every 11 years, and he would be entering a peak period between 2011 and 2012.
