Geomagnetic storms 28 June 2025

On Saturday, June 28, 2025, a kIndex of 4 indicates a moderate level of geomagnetic activity, often categorized as a "quiet" level. The kIndex scale ranges from 0 to 9, with higher values representing increased geomagnetic disturbance. At a kIndex of 4, the Earth's magnetic field experiences some fluctuations, primarily caused by solar wind interactions, but is still generally stable. For weather-sensitive individuals, this level of geomagnetic activity may have minimal yet notable effects. Some people report experiencing mild symptoms like headaches, fatigue, or mood swings during periods of heightened geomagnetic activity, even when it remains classified as "quiet." Such effects are more common among those with pre-existing conditions like migraines or anxiety disorders. While the kIndex of 4 does not typically correlate with severe disturbances, it serves as a reminder of the subtle interplay between space weather and human wellbeing. Individuals sensitive to atmospheric and magnetic changes may benefit from tracking these conditions to prepare for potential impacts on their mood or physical health.
