Fig. 1From: Validation of computed extreme ultraviolet emission spectra during solar flaresExample of GOES/XRS-B observation. The light curve of soft X-ray flux (1–8 Å) observed by the GOES/XRS-B for the M9.9-class flare on January 1, 2014 (upper panel). Light curve of soft X-ray time derivative flux (lower panel). The vertical dotted, solid, and dashed lines indicate the flare start time, peak time, and end time, respectivelyBack to article page
