Geomagnetic storms today

On July 23, 2025, a geomagnetic activity level of kIndex 5 indicates a Minor geomagnetic storm, characterized by increased fluctuations in Earth's magnetic field. This level of activity can arise from solar wind disturbances, particularly coronal mass ejections, which can affect satellite operations, GPS accuracy, and power grids. For weather-sensitive individuals, especially those with conditions like migraines, anxiety, or cardiovascular issues, this level of geomagnetic activity may lead to heightened symptoms. Some studies have suggested a correlation between geomagnetic storms and various health effects, including mood disturbances and increased stress levels, likely due to changes in electromagnetic fields. While the impact may vary from person to person, it’s advisable for those sensitive to electromagnetic changes to remain aware of these conditions and take preemptive measures, such as reducing exposure to screens and practicing relaxation techniques, during periods of increased geomagnetic activity.
