Geomagnetic storms 15 March 2025

On March 15, 2025, a geomagnetic activity level, indicated by a kIndex of 4, suggests moderately quiet magnetic conditions. The kIndex ranges from 0 to 9, with higher values representing increasingly disturbed geomagnetic activity. A kIndex of 4 indicates a state of mild disturbances that may still have some influence on the Earth's magnetosphere but is generally considered manageable. For weather-sensitive individuals, such as those with certain health conditions like migraines or cardiovascular issues, a kIndex of 4 may lead to mild symptoms, including headaches, increased fatigue, or minor mood fluctuations. Additionally, people with sensitivities to environmental changes might experience slight discomfort or unease. However, these effects are typically mild and temporary. For the general public, the impact of a kIndex of 4 is minimal; everyday activities continue ordinarily, and no drastic weather patterns are expected. In summary, while the level of geomagnetic activity can have some psychological or physiological effects on sensitive individuals, its overall impact at this level is typically benign.
