The current Kp-index. A red bar indicates extremely high auroral activity and values over 6 make aurora sightings from middle to low latitudes possible.

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