The magnetic storm that began on the evening of October 10, 2026, has ended. At its peak, it reached level G3, which corresponds to strong disturbances in Earth's magnetic field. Data from the Laboratory of Solar Astronomy of IKI RAS and ISZF SB RAS indicate the end of the storm.
Currently, the planet's magnetic field is in a state of 'calm'. According to the Laboratory of Solar Astronomy of IKI RAS and the Institute of Solar-Terrestrial Physics of SB RAS, the magnetosphere has remained in the 'green' zone for more than six hours.
The storm was the strongest in three months. A comparable event in terms of power was last recorded on July 4, 2026.
The disturbances were caused by clouds of solar plasma ejected into space during a surge in solar activity in early October. Upon reaching Earth, they affected its magnetic field.
However, the end of a magnetic storm does not mean that all disturbances disappear instantly. The geomagnetic situation may remain unstable for some time.
Magnetic storms are divided into five levels according to the international G scale — from G1 (weak) to G5 (extremely strong). The higher the level, the more noticeable the possible impact on power systems, satellite navigation, and radio communications. During a G3 storm, like the one observed on October 10, disruptions in the operation of some technical systems and auroras at unusually low latitudes are possible.
