Geomagnetic storms 23 October 2025

On Thursday, October 23, 2025, a kIndex level of 1 indicates a period of quiet geomagnetic activity. This low level of magnetic disturbance is typically associated with stable space weather, resulting in minimal impacts on Earth’s atmosphere. The kIndex, which ranges from 0 (very quiet) to 9 (extreme storm), helps measure geomagnetic activity caused by solar wind and other cosmic events. For weather-sensitive individuals, a kIndex level of 1 generally means there are no significant concerns related to geomagnetic storms. Those susceptible to such activity, including people with particular health conditions like migraines or certain types of electrical sensitivities, may benefit from the calm conditions. Typically, low geomagnetic activity can lead to fewer disruptions in high-frequency radio communications and better performance of GPS technologies. Overall, a kIndex of 1 is a reassuring sign for both everyday life and health, promoting a period of stability that is unlikely to cause weather-related discomfort for most individuals.
