Space Weather Data

This graph shows the strength of solar wind power, a real-time indicator of how strong aurora will be in about one hour. The solar wind power corresponds to the energy released by the sun over time. The more energy released, the higher the power and the stronger the aurora will be.

The solar wind power is measured by the ACE satellite just upstream of Earth and reported in units called gigawatts (1 GW = 1 billion watts). Use the following guidelines to see if an aurora might be visible in your area.
