Geomagnetic storms today

On Tuesday, January 13, 2026, a kIndex level of 4 indicates a moderate level of geomagnetic activity. While not as intense as higher levels, this level suggests increased fluctuations in the Earth's magnetic field, potentially resulting from solar wind or coronal mass ejections. For weather-sensitive individuals, a kIndex of 4 may lead to mild effects. Some people may experience headaches, fatigue, or mood changes, which have been linked to changes in geomagnetic activity. The decreased well-being in sensitive individuals can stem from the potential disruptions in sleep patterns or increases in anxiety levels often reported during such periods of activity. However, many people may not notice any significant impact. Generally, this level of geomagnetic activity is considered manageable and unlikely to cause major disruptions in daily life or weather patterns. Those with a keen interest in astrophysical events or who have medical conditions that are influenced by geomagnetic conditions should be particularly aware of these potential effects. It's advisable for them to monitor their health and well-being, adjusting routines if necessary during heightened magnetic activity.
