The solar storm, or geomagnetic, occurs when a solar wind wave attracted by the earth's magnetic field and it affects the operation of, for example, the internet. But there will at least be more demonstrations of the Northern Lights.
The storm's tenor is measured by the importance of the exchange of energy between solar wind and the magnetosphere.
The most obvious effect of this phenomenon is disturbances in radio communications, problems in electrical networks and the destabilization of the satellites sent by man to space.
Solar storms are measured on a scale of nine points divided into three categories: from G1, the mildest, to G3, the most powerful, reported site Sputnik News.
The phenomenon that began on May 14 and ends on Thursday received seven points, which corresponds to the category G3. the specialists expected it to be milder because the sun is in a minimum cycle of 11 years.
