GOES data
X-ray and energetic particle flux data from the Geostationary Operational Environmental Satellites (GOES). The National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center (SWPC) uses GOES data to produce the 1-minute averaged X-ray fluxes and 5-minute averaged energetic particle fluxes presented here.
