Geomagnetic storms 15 October 2025

On Wednesday, October 15, 2025, the geomagnetic activity level is reported as a kIndex of 3, indicating a state of quiet geomagnetic conditions. This level suggests that the Earth's magnetic field is relatively stable, with minimal disturbances typically associated with solar wind and solar activity. For weather-sensitive individuals, a kIndex of 3 generally has a negligible impact. Those who may experience effects are often individuals with heightened sensitivity to changes in atmospheric pressure or electromagnetic fields, including some migraine sufferers or people with certain chronic conditions. However, at this quiet level of geomagnetic activity, significant health or physiological disturbances are unlikely. In summary, a kIndex of 3 reflects a calm geomagnetic environment, with minimal implications for weather-sensitive populations, allowing for a normal daily experience without the potential disruptions that can sometimes occur during higher activity levels.
