Upon arrival, cause the biggest geomagnetic storm is known on our planet since 2005.The phenomenon is powerful enough to cause problems in communication satellites polar orbit.
It all started last Sunday, with a large solar flare (the third in a few days) in the central region of the Sun "The flare itself, said Doug Biesecker, a physicist Prediction Center Space Weather NOAA (National Oceanic and Atmospheric Administration) - was not particularly spectacular, but produced a coronal mass ejection extremely fast, traveling at a speed of 6.4 million km. per hour. "
The flare was of class M8, 7 (pictured), much more powerful than the previous two (C6 and M3). Solar flares are classified according to their intensity, with the letters A, B, C, M and X followed by a number from 1 to 9. A M8, 7, then, is very close to the maximum intensity.
According to data compiled by the Center Goddard Space Weather, NASA, the coronal mass ejection (the cloud of ejected burning particles and radiation from the sun) moved yesterday to at least 2253 km. per second towards the Earth, and is expected to hit Earth's magnetosphere (the "shield" that protects natural magnetic planet of such events) during the day Tuesday.
The scale of the guarantee, once again, spectacular auroras, even farther south than usual. With respect to the geomagnetic storm (the disturbance of the magnetosphere caused by the cloud of solar material) will be the largest suffered by our planet since 2005.
However, its intensity is considered "medium high", so it has been classified as "strong" but not "severe" or "extreme".
This means that, for example, be able to cause failure of the computers on board the satellites in orbit and interfere with radio communications in the polar zone. These risks will remain until tomorrow, Wednesday.
The geomagnetic storm could also affect some commercial flights in the northern hemisphere, the oil refineries and communications science missions in the Arctic.
