This GOES X-ray flux plot contains 5 minute averages of solar X-ray output in the 1-8 Angstrom (0.1-0.8 nm) and 0.5-4.0 Angstrom (0.05-0.4 nm) passbands. Data from both operational GOES satellites are included. Some data dropouts will occur during satellite eclipses. SEC alerts are issued at the M5 (5x10E-5 Watts/m2) and X1 (1x10E-4 Watts/m2) levels, based upon 1-minute data. Large X-ray bursts cause short wave fades for HF propagation paths through the sunlit hemisphere. Some large flares are accompanied by strong solar radio bursts that may interfere with satellite downlinks.
