Geomagnetic storms 19 October 2025

On Sunday, October 19, 2025, the kIndex level of geomagnetic activity is recorded at 4, indicating a state of typically quiet geomagnetic conditions. The kIndex ranges from 0 to 9, where levels below 4 generally signify minimal disturbances in the Earth's magnetic field. A kIndex of 4 suggests minor fluctuations, often resulting from solar wind and coronal mass ejections but not strong enough to cause significant geomagnetic storms. For weather-sensitive individuals, this level of geomagnetic activity may result in mild physical sensations such as fatigue, headaches, or irritability, although such symptoms are relatively uncommon at this level. Individuals who are particularly sensitive to electromagnetic changes, including those with certain health conditions or those using pacemakers, might experience subtle changes in mood or energy levels. Overall, while a kIndex of 4 denotes manageable geomagnetic conditions, it's essential for sensitive individuals to remain observant of their well-being and adjust daily routines as necessary.
