Geomagnetic storms 14 September 2025

On Sunday, September 14, 2025, the geomagnetic activity level, denoted as kIndex, registers at 4. This level indicates a moderate state of geomagnetic activity, typically characterized by occasional disturbances in the Earth's magnetic field. While this level is not severe, it can still produce visual auroras in higher latitude regions. For weather-sensitive individuals, such as those with certain medical conditions or those prone to migraines, a kIndex of 4 may have mild effects. Fluctuations in geomagnetic activity can impact the body’s circadian rhythms and may lead to increased feelings of fatigue or irritability in some people. Individuals with pre-existing conditions, like cardiovascular issues, might experience mild discomfort or heightened anxiety during such geomagnetic events. Overall, while a kIndex of 4 is considered "quiet" by geomagnetic standards, its variable effects on human health and well-being still warrant attention, particularly for those sensitive to changes in environmental conditions. Regular monitoring and self-awareness can help mitigate any adverse effects experienced by sensitive individuals during periods of geomagnetic activity.
