Geomagnetic storms 13 January 2026

On Tuesday, January 13, 2026, a geomagnetic activity level (kIndex) of 3 indicates a quiet level of geomagnetic fluctuations. This means that the Earth's magnetic field is relatively stable, with minimal disturbances from solar wind and cosmic rays. In this state, the likelihood of significant auroral activity or geomagnetic storms is low, providing a predictable and calm environment for various terrestrial systems. For weather-sensitive individuals, a kIndex of 3 typically has little to no impact. People who are prone to migraines, joint pain, or other weather-related sensitivities may not notice any adverse effects linked to geomagnetic activity. Instead, this level usually corresponds to stable weather conditions, which can be favorable for outdoor activities and overall well-being. In summary, a kIndex of 3 signifies a period of tranquility in geomagnetic activity, resulting in a generally positive outlook for weather-sensitive individuals and minimal interference with daily life.
