The largest solar flares seen in five years are sending a mass of charged particles toward Earth, which can cause radio interference and aurora borealis.
According to NASA, the Sun unleashed a M-2 (medium) solar flare, a kind of radiation storm S1 (minor) and a spectacular coronal mass ejection (CME) June 7, 2011, from complex, in 1226 -1227 . A large cloud of particles increases and decreases the appearance as if covered an area almost half the solar surface.
U.S. National Weather Service (NWS), said in a statement that the solar flare has issued an unprecedented influence since 2006, with the current measured by NASA as M-2 medium-sized solar flare, which is "a large ejection ejections coronal mass (CME) ... and is visually spectacular. "
According to the model of NASA, the CME is moving at 1400 km / s. This storm will not directly hit the ground radiation, but also provide "a shot in search" in the Earth's magnetic field during the late hours of June 8 June 9.
The flames were accompanied by a coronal mass ejection or CME, which is a cloud of hot charged particles moving at high speed toward the outer surface of the donation. The flames are seen in the first place, as light and radiation only eight minutes to reach Earth. The CME is moving more slowly and takes days, as thunder follows lightning.
Solar flares occur because the sun's magnetic field is a complicated way. Earth's field is like a giant magnet, with some lines from the north and south poles and elegant way to describe a ring, etc..
Sky watchers at high latitudes to be careful sunrise or aurora borealis, also known as aurora borealis, which was created as a result of a natural mechanism between the solar wind, ions flowing, the earth's magnetic field and collisions between ions and atoms and molecules in the atmosphere that cause the release of energy in the form of colored lights.
The Aurora Borealis (Northern Lights) and Aurora Australis (Southern Lights) will probably be visible on the afternoon of June 8 and 9. With the sun that illuminates most of the auroral zone in Russia and Scandinavia, the aurora is most visible in North America.
Visible auroral activities are planned for Thursday and Friday as well as the head of Inuvik, Yellowknife, Rankin, Iqaluit and its surroundings. Visibility can be low on the horizon in Seattle, Des Moines, Chicago, Cleveland, Boston and Halifax, on Thursday, and Prince Rupert, Calgary, Minot, Bemidji, Stevens Point, Traverse City and Quebec City, Canada on Friday.
If a large solar flare increases the chance of a light show, the electromagnetic pulse can disrupt satellite communications, power grids and radio traffic that passes the Earth. Some industries that are typically affected by solar storms are the power grid companies, airlines, GPS, military and maritime routes.
Rockets send X-ray bursts and charged particles - mostly protons - from the sun's surface into space. Sometimes it is headed toward Earth. They are classified according to how powerful they are, as A, B, C, F, X, where X is the most powerful. The rocket was detected SDO M-class rocket June 7.
The last major solar eruption occurred in 2006, and were more powerful in 2005 and 2003 as well. The most powerful ever recorded was in 1859 and was strong enough to damage equipment.
