Geomagnetic storms 14 November 2025

On Friday, November 14, 2025, with a kIndex of 4, geomagnetic activity is classified as moderate to quiet. The kIndex, which ranges from 0 to 9, measures disturbances in Earth's magnetic field, influenced by solar wind and coronal mass ejections. A kIndex of 4 indicates some fluctuations but is generally not associated with severe geomagnetic storms. For weather-sensitive individuals, this level of geomagnetic activity may not cause significant physical symptoms, but some people, particularly those with certain health conditions, might experience mild effects. Symptoms can include headaches, fatigue, or mood fluctuations, often linked to changes in the Earth's magnetic field. Additionally, those who rely on technologies like GPS or satellite communications may experience slight disruptions, though they are typically manageable. In summary, while a kIndex of 4 suggests a relatively calm environment, it may still have minor impacts on individuals sensitive to climatic and electromagnetic changes, necessitating awareness among those affected.
