Welcome to the Real Time Dst Estimate Web Page

Current Geo-Magnetic Storm Level Based on ACE Real Time Solar Wind Data





Please click on dial to see Geo-Magnetic Storm Level for today. Dst values are extrapolated using most recent solar wind and magnetic field data when data gaps are present.

Low: Dst > -20 nT

Medium: -20 nT > Dst > -50 nT

High: -50 nT > Dst > -100 nT

Extreme: Dst < -100 nT
