Geomagnetic storms 6 November 2025

On Thursday, November 6, 2025, the kIndex level of geomagnetic activity is recorded at 4, indicating a quiet level of geomagnetic disturbances. The kIndex, ranging from 0 to 9, quantifies geomagnetic activity based on observed fluctuations; a level of 4 suggests minor disturbances but generally stable conditions. For weather-sensitive individuals, such as those with certain medical conditions or those prone to migraines and mood fluctuations, a kIndex of 4 may still elicit mild effects. Some people report heightened sensitivity to geomagnetic fluctuations, even at lower activity levels. These effects may include slight changes in mood, energy levels, or minor headaches, but the overall impact is typically not severe. Considering that geomagnetic activity can influence the Earth's atmosphere, individuals who are especially attuned to climatic shifts—such as those involved in climate-related activities or aviation—may experience brief adjustments in their routines. However, at this kIndex level, significant disruptions or acute health issues are unlikely. Overall, the impact of a kIndex of 4 on weather-sensitive people remains manageable and typically mild.
