Geomagnetic storms 17 November 2025

On November 17, 2025, a geomagnetic activity level of 5 indicates a Minor geomagnetic storm, as measured by the k-index. This level of activity can result from solar wind disturbances and coronal mass ejections, which interact with the Earth’s magnetic field. While a k-index of 5 is not particularly severe, it may still have noticeable effects, particularly for individuals sensitive to weather changes. People with certain health conditions, such as migraines or cardiovascular issues, may experience exacerbated symptoms during periods of heightened geomagnetic activity. Additionally, fluctuations in the Earth's magnetic field can affect sleep patterns and mood, potentially leading to increased anxiety or irritability. Weather-sensitive individuals should be aware of these potential symptoms and monitor their health during such events. Overall, while the geomagnetic storm's impact on daily life is typically limited, it is important for those sensitive to magnetic fluctuations to take precautions if they notice any changes in their well-being during these periods of increased geomagnetic activity.
