A powerful magnetic storm triggers the aurora around the world

This geomagnetic storm received the index G3 (Kp7) Visible at latitude 50. Geomagnetic storm is a disturbance of the geomagnetic field lasting from several hours to several days. Along with substorms, geomagnetic storms are one of the types of geomagnetic activity. They are caused by the arrival of disturbed streams of the solar wind in the vicinity of the Earth and their interaction with the Earth’s magnetosphere. Geomagnetic storms are a manifestation of the intensification of the Earth’s ring current, which constantly exists in the area of ​​the Earth’s radiation belts. This phenomenon is one of the most important elements of solar-terrestrial physics and its practical part, usually denoted by the term “space weather“
