Geomagnetic storms 16 September 2025

On September 16, 2025, a kIndex level of 3 indicates a quiet level of geomagnetic activity. This level suggests minimal disturbances in the Earth's magnetic field, resulting in stable atmospheric conditions. During times of kIndex 3, geomagnetic storms are unlikely, meaning that solar winds and solar flares are not significantly impacting Earth's magnetosphere. For weather-sensitive individuals, such as those who suffer from migraines or other health conditions influenced by atmospheric changes, this quiet geomagnetic state typically means fewer weather-related symptoms. They may experience a sense of relief, as stable geomagnetic conditions are often associated with reduced fluctuations and irritability in the weather. As a result, people might find it easier to engage in outdoor activities and enjoy better overall well-being. However, it’s worth noting that while a kIndex of 3 indicates stability in geomagnetic terms, individual reactions to atmospheric conditions can vary, and other meteorological factors should also be considered for a holistic understanding of weather sensitivity.
