Geomagnetic storms 13 October 2025

On Monday, October 13, 2025, a kIndex of 3 indicates a level of geomagnetic activity that is classified as "quiet." This level signifies stable geomagnetic conditions, typically characterized by minimal disruptions in the Earth's magnetic field. These quiet conditions are generally devoid of significant solar storms or solar wind activity, making for a relatively calm environment in terms of space weather. For weather-sensitive individuals, such as those with certain health conditions or heightened sensitivities to magnetic fields, a kIndex of 3 is unlikely to produce noticeable effects. People who may experience discomfort or changes in mood due to geomagnetic fluctuations are less likely to be impacted at this level. However, they should remain aware of the potential for changes in solar activity, as even slight variations can affect some individuals. Overall, a kIndex of 3 contributes to a normal daily routine, minimizing disruptions associated with geomagnetic phenomena.
