Geomagnetic storms 4 November 2025

On November 4, 2025, the geomagnetic activity is at a kIndex level of 3, which is classified as a "quiet" level of magnetic activity. At this level, the Earth's magnetic field experiences minimal disturbances, suggesting stable conditions for both natural phenomena and human activities. For weather-sensitive individuals, a kIndex of 3 typically indicates a lower likelihood of significant geophysical effects, such as disruptions in satellite communications or navigational systems. However, some people may still experience mild symptoms associated with geomagnetic activity, including headaches, fatigue, or changes in mood. While these effects are generally not pronounced at this level, heightened awareness is advisable for those sensitive to changes in their environment, as they may still respond to subtle shifts in geomagnetic conditions. Overall, a kIndex of 3 signifies a relatively calm period, making it a favorable day for outdoor activities and lessening the risk of discomfort among those prone to weather-related sensitivities.
