Space Weather Overview

Latest Space Weather Overview image

These plots provide a quick look at some of the most frequently examined space weather indices.

Three day plots of the Solar X-ray Flux with flare designations, the Solar Proton Flux in proton flux units (log scale) and Geomagnetic Activity as indicated by the Planetary K-index.

These plots are produced and available on the SWPC website.
