A powerful magnetic storm on Earth will continue until at least November 7, Maria Abunina, head of the IZMIRAN Space Weather Forecasting Center, announced on November 6. According to her, the disturbances are caused by rapid coronal mass ejections (CMEs) heading toward our planet.

According to IZMIRAN data and solar activity observations, a series of coronal mass ejections (CMEs) from the Sun triggered a strong period of geomagnetic disturbances. Two large and rapid CMEs in the previous 24 hours increased the likelihood of a further intensification of the magnetic storm; their arrival at Earth is expected within the next day, which could lead to increased geomagnetic activity.

On November 6, the press services of the solar astronomy laboratories at the Space Research Institute (IKI) and the Institute of Solar-Terrestrial Physics (ISTP) of the Russian Academy of Sciences (RAS) reported that planetary-scale magnetic storms began on Earth on the night of November 6, with geomagnetic field disturbances reaching G2–G3 levels. Currently, the geomagnetic index Kp fluctuates between 6–7, corresponding to a moderate to strong level of disturbance.

Experts warn that, in addition to disruptions to electronic and navigation systems, increased geomagnetic activity can negatively impact the well-being of weather-sensitive individuals, including increased fatigue, headaches, and cardiovascular symptoms. Recommendations include limiting time outdoors during peak periods, avoiding intense physical activity, and monitoring sensitive electronics and satellite services.

"A major magnetic storm has truly begun, and there will be another one tomorrow. It's likely a bit more powerful, because yesterday the Sun experienced coronal mass ejections—two large, powerful, fast ejections, which we expect to arrive tomorrow during the day," she said in an interview with kp.ru.

Coronal mass ejections—large streams of plasma and magnetic field ejected from the surface of the Sun—can trigger geomagnetic storms when they collide with Earth's magnetosphere. The intensity of their effects is measured by indices, including Kp; values of 6–7 indicate significant disruptions that could affect power grids, radio communications, satellite systems, and the health of sensitive individuals. Peak activity is predicted for November 7, 2025.
