Top 50 tempestes geomagnètiques de 2021

On this page you will find an overview of the strongest geomagnetic storms of 2021 together with links to more information in our archive. Storms are ranked by the Disturbance storm-time index (Dst) that is designed to measure the magnetic signature of magnetospheric currents observed in the equatorial regions. The Dst index is provided by the World Data Center for geomagnetism in Kyoto.
