Geomagnetic storms 28 November 2025

On November 28, 2025, a kIndex of 4 indicates a level of geomagnetic activity that is considered relatively quiet, categorized as a minor disturbance. Typically, a kIndex ranges from 0 to 9, with higher values correlating to increased geomagnetic storms. A kIndex of 4 suggests that while some fluctuations in the Earth's magnetic field may be occurring, they are not severe enough to cause widespread disruptions. For weather-sensitive individuals, particularly those susceptible to changes in geomagnetic conditions, a kIndex of 4 may lead to mild symptoms. Some may experience headaches, mood swings, or changes in sleep patterns, especially those with a history of sensitivity to geomagnetic variations. However, the effects are generally not significant at this level, and most people may not notice any impact at all. Overall, while a kIndex of 4 indicates a tranquil state of geomagnetic activity, awareness of these fluctuations can be beneficial for those who are particularly attuned to their effects on well-being.
