Solar Cycle 25 - Top 50 geomagnetic storms
On this page you will find an overview of the strongest geomagnetic storms from Solar Cycle 25 together with links to more information in our archive. The Kp-values on this page are the official, finalized Kp-values from the GFZ in Potsdam, Germany. The Ap-index provides a daily average level for geomagnetic activity. The Ap-index is thus a storm-index where long geomagnetic storms have a higher daily Ap-value. This page is updated daily. Times are in UTC.
