MOSCOW, April 6 — RIA Novosti. Magnetic storm began on Earth on Wednesday night — the index of geomagnetic disturbances Kp reached a value of 6, one more than the minimum value, which is considered a storm, according to the space weather forecast center of the National Oceanic and Atmospheric Administration of the USA (NOAA).
Level of magnetic disturbance began to grow around 15.00 to 18.00 MSK and reached the "red zone." Currently, the index Kp, characterizing the geomagnetic activity has reached a value of 6. This scale has 10 levels, from 0 to 3 are the quiet magnetosphere, level 4 — perturbed, and the levels of 5 to 9 — magnetic storms five classes.
Magnetic storm can "hold" the whole day, because it caused an exceptionally powerful ejection of plasma on the sun, told RIA Novosti the Laboratory of X-ray astronomy of the Lebedev Physical Institute (LPI) Sergey Bogachev.
"It was a long coronal mass ejection, which began on the night of April 2. He walked from the southern hemisphere of the Sun, and while he was traveling in the plane of Earth's orbit, but it was not directly on the earth, "- said Bogachev.
Disturbances in the Earth's magnetosphere — the magnetic storms — occur under the action of solar plasma of charged particles ejected Sun. Particles, "kick" of the magnetosphere, forcing it to vibrate, which can cause disruptions in radio.

"We argued, it was not clear, this release gets to the earth or not. But still got "- said Bogachev.
"Release was unusually strong. Storm last night at least, "- he added.
