Geomagnetic storms 17 January 2026

On Saturday, January 17, 2026, the kIndex level is recorded at 4, which indicates a moderate level of geomagnetic activity. KIndex values range from 0 to 9, with lower numbers signifying quiet conditions and higher numbers indicating increased geomagnetic disturbances. A kIndex of 4 generally means that the Earth’s magnetosphere is experiencing some fluctuations in its magnetic field, primarily influenced by solar wind and solar activity. For weather-sensitive individuals, this moderate activity can lead to subtle changes in mood and well-being. Some people may experience mild symptoms such as headaches, fatigue, or heightened anxiety during periods of increased geomagnetic activity. Those with existing conditions like migraines or mental health disorders might be more susceptible to these fluctuations. However, most people may not notice significant effects at this kIndex level. It’s advisable for sensitive individuals to maintain awareness of their health and well-being, especially when geomagnetic conditions fluctuate. Overall, while a kIndex of 4 indicates a degree of activity, it is generally not associated with severe impacts on health or daily life.
