There was the largest solar flare ever observed


10/06/2011

Mushroom cooled plasma popped like a pimple on the sun, and then, under the force of gravity, hit back. In the space has been thrown out the largest amount of solar material on record.

Solar flare - an unusually bright spot in the sun, does not surprise scientists. Space observatories over the past year recorded about 70 such outbreaks, each of which is about ten times weaker than "extreme" flare, which since 2007, there was only two.

Scientists amazed the amount of material that was ejected by the sun, has grown in size and has fallen back to about half the solar surface. Ejection of matter outer layers of the solar atmosphere (corona) vybroom called coronal mass (CME).

"It came as a complete surprise. At this point, little has happened, but as soon as she came out from behind the sun, suddenly there was a flash and a huge release of particles," - said astrophysicist Phillip Chamberlin of the Solar Dynamics Observatory, which, among others, This phenomenon was observed.

"We have never seen such a huge CME."

According to Chamberlin, the calculation of the mass of the electrons and protons, escaped into space, it will take some time. But he noted that the amount of space ejection hundreds of times greater than the volume of the Earth.

Particle emissions occurred on the right edge of the disk of the sun, so they will pass Earth at the aurora can become brighter.

Experts in the field of space weather to express their concern for the future development of events.

11-year cycle of solar activity, with tangled magnetic field, its surface reaches its peak in late 2013 or early 2014.

"We’re probably going to see [extreme] flashes every few months, not years" - said Chamberlin.

In the event that such a powerful flare and coronal mass ejection touches the Earth, the charged particles will fall to the satellites, carrying the potential threat to their operation.

On the surface of the planet, so many solar particles will strengthen the electrical current in electrical networks and heats them. Solar storm in 1859, for example, burned telegraph lines. Although power plants are taking appropriate steps and try to evenly distribute the load to prevent the development of such a scenario, energy, solar storms can blow transformers and lead to blackouts, especially in hot weather.

"Despite all the precautions, electricity distribution network is still vulnerable," - said Chamberlin.
