Geomagnetic storms 30 November 2025

On Sunday, November 30, 2025, a kIndex level of 4 indicates a moderate level of geomagnetic activity. This level, while higher than quiet (0-3), is still generally considered stable with only minor fluctuations in the Earth's magnetic field. Individuals may experience slight effects, such as increased auroras in higher latitudes, but the overall impact is minimal. For weather-sensitive people, a kIndex of 4 might cause mild disturbances to certain electronic devices, potentially affecting GPS accuracy, radio communications, and power grid operations. However, these effects are usually transient and not severe. Some individuals sensitive to electromagnetic changes may report slight variations in mood or sleep patterns, attributed to the heightened magnetism. Overall, a kIndex of 4 does not signify significant disruptions, but people who are sensitive to geomagnetic changes should remain aware of the potential for minor fluctuations in their environment.
