Afgelopen weekend krachtige zonnevlammen gemeld.. ( http://www.swpc.noaa.gov/rt_plots/xray_5m.html)

The 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 the SWPC Primay GOES X-ray satellite is shown. As of Feb 2008, no Secondary GOES X-ray satellite data is available. Some data dropouts will occur during satellite eclipses.

Other plots of interest: A black background version of this plot; GOES 1-min X-rays; SWPC Real-time Monitors.

SWPC X-ray 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.
