Geomagnetic storms 13 April 2025

On Sunday, April 13, 2025, a geomagnetic activity level of 4 indicates a moderate level of magnetic disturbance, categorized as a "quiet" level in the kIndex scale. This means that while geomagnetic activity is not extreme, some fluctuations may still occur due to solar wind interactions with the Earth's magnetic field. For weather-sensitive individuals, a kIndex of 4 may lead to minor disturbances. Those with conditions sensitive to electromagnetic changes, such as migraines or certain cardiovascular issues, might experience mild symptoms, including headaches or increased fatigue. Additionally, this level of geomagnetic activity can influence atmospheric conditions, which could also affect individuals with respiratory issues. Overall, while a kIndex of 4 suggests stability in geomagnetic conditions, it is advisable for sensitive individuals to remain mindful of potential mild health impacts and to stay informed about local weather and solar activity updates.
