Geomagnetic storms today

On November 13, 2025, a kIndex of 8 indicates a Severe geomagnetic storm, characterized by intense fluctuations in the Earth's magnetic field. This level of activity often results from significant solar events, such as coronal mass ejections (CMEs), which can enhance the interaction between solar wind and the Earth's magnetosphere. For weather-sensitive individuals, particularly those with conditions like migraines or cardiovascular issues, a Severe geomagnetic storm can exacerbate symptoms. Reports suggest that increased geomagnetic activity may correlate with heightened levels of anxiety, fatigue, and sleep disturbances. Additionally, individuals with electronic medical devices, such as pacemakers, may experience interference if exposed to extreme electromagnetic conditions. While most people are not directly affected, those particularly sensitive to environmental changes could feel the impacts more acutely. Being aware of geomagnetic storms can help mitigate potential discomfort by encouraging sensitive individuals to take precautions, such as managing stress levels and monitoring their health.
