The GOES X-ray flux plot contains 1 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.

GOES 10 Decommissioning Dec 1, 2009
GOES 14 Becomes Primary Satellite for XRS data

November 17, 2009 -- On Tuesday, 01 December, the GOES 10 satellite will be officially decommissioned. At that time, GOES 14 will replace GOES 10 as the Primary SWPC GOES X-ray Satellite.

Changes to the GOES XRS Data

The GOES 10 and GOES 14 XRS instruments have very different electronics and therefore, there will be some qualitative changes in the appearance of the data. The main difference will be the level of noise in the data at the lowest values. When the background levels are low (less than 2E-7 W/m2 or A2.0), the GOES 10 data looks flat and the steps are very abrupt. At these low flux levels, the GOES 14 data will be quite noisy. As the x-ray flux levels rise up above 2E-7, the noise will decrease and the plots will look very similar to the GOES 10 data.

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.
