Top 50 des tempêtes géomagnétiques de 2023

Sur cette page, vous trouverez un aperçu des tempêtes géomagnétiques les plus fortes de 2023 ainsi que des liens vers des informations complémentaires dans nos archives. 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.
