Geomagnetic storms today

On Friday, January 16, 2026, a kIndex of 4 indicates a moderate level of geomagnetic activity. This level is characterized as "quiet" to "unsettled," suggesting that geomagnetic storms are generally absent, and solar wind conditions are relatively stable. For weather-sensitive individuals, the impact of this level of geomagnetic activity is typically minimal. While people with specific sensitivities, such as those experiencing migraines or certain cardiovascular conditions, may feel slight effects due to the interaction of geomagnetic fields with the Earth's atmosphere, most individuals are unlikely to experience significant disruptions. In general, a kIndex of 4 does not usually lead to widespread phenomena such as auroras or severe disruptions in technology. However, some people may report minor fluctuations in mood or energy levels, potentially linked to changes in atmospheric pressure or solar activity. Overall, while a kIndex of 4 reflects moderate geomagnetic activity, it is often considered safe and stable for the general population, with minimal impacts on health or daily life.
