Geomagnetic storms 18 November 2025

On November 18, 2025, the kIndex level of geomagnetic activity is recorded at 3, indicating a quiet state of geomagnetic conditions. The kIndex ranges from 0 to 9, with lower values reflecting minimal disturbances in Earth's magnetic field. At a level of 3, there may be occasional fluctuations, but overall, the environment remains relatively stable. This tranquility offers a respite from more intense geomagnetic activity, which can influence technological systems and natural phenomena. For weather-sensitive individuals, a kIndex of 3 is unlikely to cause significant issues. People with heightened sensitivities to changes in atmospheric conditions—such as those suffering from migraines or other chronic health issues—might experience minimal impact. However, those with particular adverse reactions to geomagnetic disturbances may find this quiet period beneficial, as it is less likely to exacerbate existing conditions. In summary, a kIndex of 3 signifies a calm period, promoting stability for both the environment and individuals sensitive to geomagnetic changes.
