A powerful magnetic storm has hit the Earth, the strongest in three months: how long will it last?

As reported on October 11 by specialists from the Solar Astronomy Laboratory of the Institute of Space Research, the magnetic storm reached the third level on a five-point scale of geomagnetic activity. The last time a magnetic storm of comparable strength was observed was on July 4, 2026. Thus, the current storm has become the most intense since early July. The cause of the geomagnetic disturbances was clouds of solar plasma ejected into space during a surge of solar activity earlier in the week. Upon reaching Earth, the streams of charged particles caused strong fluctuations in the planet's magnetic field. **What are the dangers of a G3 level magnetic storm?** According to international classification, a G3 level is considered a strong magnetic storm. Such phenomena can cause disruptions in satellite systems, radio communications, and navigation equipment. In some cases, voltage fluctuations in power grids may occur. As for the impact of magnetic storms on human well-being, there is currently insufficient scientific evidence to convincingly prove that they directly cause headaches, blood pressure spikes, or other common symptoms. **When will the magnetic storm end?** According to specialists' forecasts, geomagnetic disturbances may continue for approximately another 24 hours. This means that the increased activity of Earth's magnetic field may persist into Monday, October 12. At the same time, the intensity of the storm can vary throughout the day, so scientists continue to monitor solar activity and the state of Earth's magnetosphere.
