Light curves of the M1.1 flare from 14:30 UT to 15:00 UT on 2023 May 25. Panel (a) shows GOES SXR fluxes at wavelengths of 1−8 Å (solid black line) and its derivative (dotted blue line), and HXI HXR count rates in the energy bands 13−18 keV (solid red line) and 19−30 keV (solid cyan line). Panel (b) shows normalized light curves of CHASE Hα waveband and AIA 94, 131, 171, 193, 211, 304, and 335 Å channels from the brightening region, as shown in the black box in Figure 1b.
