Real-Time Solar Wind data from NASA's ACE satellite.
Dials are updated every 5 minutes with
data averaged over last 15 minutes.

Current Geo-Magnetic Storm Level
Low: Dst > -20 nT

Medium: -20 nT > Dst > -50 nT

High: -50 nT > Dst > -100 nT

Extreme: Dst < -100 nT

The Dst is a geomagnetic index which
monitors the world wide magnetic storm level.

STEREO consists of two space-based observatories - one ahead of Earth in its orbit,
the other trailing behind. With this new pair of viewpoints, scientists will be able to see
the structure and evolution of solar storms as they blast from the Sun and move out through space.

Auroral Ovals


The graphics above show the current extent and position of the auroral oval at each pole, extrapolated from measurements taken during the most recent polar pass of the NOAA POES satellite.
"Center time" is the calculated time halfway through the satellite's pass over the pole.
The red arrow in the plot, that looks like a clock hand, points toward the noon meridian.
