Top 50 geomagnetic storms of 2023

On this page you will find an overview of the strongest geomagnetic storms of 2023 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.

Current data suggests there is a slight possibility for aurora to appear at the following high latitude regions in the near future

Oulu, Rovaniemi, Sodankylä, Utsjoki
Reykjavik
Kirkenes, Tromsø
Arkhangelsk, Murmansk, Norilsk, Vorkuta
Kiruna, Luleå

The solar wind speed is currently moderately high (673.3 km/sec.)

The direction of the interplanetary magnetic field is slightly South (-7.86nT).

The maximum X-ray flux of the past two hours is:
