Powerful magnetic storm covered the Ground

After another coronal mass ejection that was observed in the Sun last weekend, the Earth reached a strong magnetic storm. So, on August 17, our planet will be a strengthening of negative trends geomagnetic environment.

Peak on August 18, during the period from midnight until 3 o'clock in the afternoon, then the perturbation of the magnetic field will be less solid.

Solar activity has increased significantly on August 16 Sunday, which angered the geomagnetic field of the Earth. As explained Heliogeophysical service of Federal state budgetary institution "Institute of applied Geophysics", in the southwest quadrant of the visible Solar disk on 12 August at 17:48 Moscow time was recorded coronal mass ejection.

"He accompanied the collapse of the solar fiber and long (141 minutes) the flash (class) B 7.0 (S27W27, the peak time of 18:26 Moscow time). The CME (coronal mass ejection) has a component directed towards the Earth. The discontent of the geomagnetic field may 16 August", - is told in the news of the Institute.

According to reliable information Heliogeophysical service, August 13 on the Solar disk was observed 3 groups of spots. In the group 2396 (S18W79) was registered 1 splash of class B. According to the forecast of scientists, in the coming days on our sun flare activity expected to be low, the geomagnetic field is quiet, but with occasional periods of instability.

Note that solar flares, depending on the capacity of x-ray radiation are divided into 5 classes A, B, C, M and X. Minimum class A0.0 corresponds to the radiation power at the Earth's orbit in 10 nanowatt per square m. In the transition to the upcoming letter power increases 10 times. Powerful flash under certain conditions, one of which is their tendency towards the planet, can cause magnetic storms on Earth.

Magnetic storms occur in the result of the interaction of the magnetized high-speed streams of solar plasma with the Earth's magnetosphere. Actually, this is a reaction of the magnetic field of the Earth on to outbreaks occurring in the Sun. The Earth's magnetic field - a kind of protective dome that reflects attacks from space. The danger is not only the radiation coming from the sun, but other sufficiently strong radiation. That's specifically a "protective" response of Earth's magnetic field, the result of which can sometimes be rapid and strong change data of the electromagnetic field of the planet and is called a magnetic storm.
