Geomagnetic storms today

On Thursday, November 20, 2025, with a geomagnetic activity level (kIndex) of 4, this signals a "quiet" level of geomagnetic activity. A kIndex of 4 indicates minor disturbances in the Earth's magnetic field but generally remains stable. In this context, the impact on weather-sensitive individuals is relatively low. While such levels of geomagnetic activity are often associated with subtle fluctuations in the ionosphere, the likelihood of significant disruptions to daily life or health is minimal. However, some people who are particularly sensitive to geomagnetic variations may experience mild symptoms, such as headaches, fatigue, or slight mood changes, as their bodies respond to the magnetic changes. Overall, the kIndex of 4 represents a stable environment where the effects are mostly benign for the general population, with any disturbances being more psychological than physiological. Weather-sensitive individuals should monitor their symptoms but may not need to take specific precautions during this phase of geomagnetic activity.
