GOES X-Ray Data from Noaa.jpg (11013 bytes)


This plot shows measurements of the soft x-ray flux from the Sun over a time interval of three days (Universal Time). The data were obtained by a detector on each of two GOES weather satellites. Each detector observes in two soft x-ray energy bands. Therefore the plot shows four curves. The letters on the right side of the plot (A, B, C, M, X) represent a classification scheme for the intensity of flares. A flare is a C flare if its peak flux falls between 10-6 and 10-5 Watts m-2. The peak flux of an M flare falls between 10-5 and 10-4 Watts m-2.

The inner circle shows the size of the visible disk of the Sun.  The blue disk is the region occulted by the Large Angle and Spectrometric Coronograph (LASCO).
