Geomagnetic storms today

On Saturday, November 1, 2025, a geomagnetic activity level (kIndex) of 4 indicates a moderate level of magnetic disturbances, though it is still considered relatively quiet. The kIndex scales range from 0 to 9, with higher values reflecting increased geomagnetic turmoil often triggered by solar events. A kIndex of 4 signals that geomagnetic storms may lead to minor disruptions in Earth’s magnetic field, potentially affecting satellite operations and radio communications, particularly in high-latitude regions. For weather-sensitive individuals, such as those with certain health conditions, moderate geomagnetic activity can influence mood and well-being. Some studies suggest that fluctuations in geomagnetic fields may correlate with changes in sleep patterns, anxiety levels, and even physical discomfort for specific individuals. Those prone to migraines or other weather-related sensitivities might also notice heightened symptoms. While the impact is typically mild, awareness of geomagnetic conditions may assist in managing these sensitivities, allowing individuals to adjust their activities in response to fluctuations in magnetic energy.
