Geomagnetic storms today

On Tuesday, October 7, 2025, a geomagnetic activity level (kIndex) of 4 indicates a state of moderate disturbance in the Earth's magnetic field, categorized as "quiet" overall within the scale of geomagnetic activity. This level typically suggests minor fluctuations in the geomagnetic field that may not significantly affect most daily activities or technical systems. For weather-sensitive individuals, the impact of a kIndex of 4 is generally mild. Some people may experience subtle changes in mood or energy levels, often influenced by the electromagnetic activity. This level may slightly affect those who are particularly sensitive to geomagnetic fluctuations, potentially leading to increased fatigue or irritability. However, for the majority, this level is unlikely to cause any noticeable health concerns or disruptions in daily life. In summary, while a kIndex of 4 indicates a moderate level of geomagnetic activity, its effects on weather-sensitive individuals are typically minimal, promoting awareness rather than alarm.
