Powerful X-Ray Flares

Powerful X-Ray Flares

. The X-ray activity of the Sun is monitored by the Geostationary Operations Environmental Satellites, or GOES. The GOES data shown here includes three exceptionally intense, X-class flares emitted from the same active region on 6 and 7 June 2000. The first two flares were also associated with a powerful coronal mass ejection observed with an instrument aboard the SOHO spacecraft (Fig. 8.15). The GOES data are collected by the National Oceanic and Atmospheric Administrationís Space Environment Center and distributed to all interested persons though its space weather forecasts.
