Space Weather Forecast

Conditions in the Solar Wind and the Interplanetary Magnetic Field, measured by satellites roughly 45 minutes "upstream" or "sunward" of Earth, provide us with early warning of storms headed towards our planet.

The dials below are maintained by scientists from Rice University using data from the ACE spacecraft.

Density of the Solar Wind
Units of protons per cubic cm

Pressure of the Solar Wind
Units of nanopascals

IMF (Interplanetary Magnetic Field) Conditions
