The Sun emitted another mid-level (M8.1) flare from the same active region (AR 2673) on Sept. 8. Solar flares are sudden outbursts of energy that dramatically enhance the X-ray region of the solar spectrum. The Geostationary Operational Environment Satellites (GOES) classifies flares based on their X-ray emission peaks (A, B, C, M or X). On each GOES satellite there are two X-Ray Sensors (XRS) which measure X-ray brightness of flares in the wavelength range of 0.5 to 3 Angstroms (black line) and 1 to 8 Angstroms (red line). You can see the measurements above. The imagery/data dropouts are due to satellite eclipses.
