a: SXR light curves of the flare in 0.5−4 Å and 1−8 Å. The magenta dashed line represents the background intensity. b: time derivative of the flux in 1−8 Å (black line) and HXR light curve at 12−25 keV (orange line). The red dashed lines denote the peak times of two-stage energy release. c: time evolution of the flare temperature (T_e) and the emission measure (EM) derived from GOES observations. d and e: time evolution of the integral intensity of the flare in 131 Å and 335 Å. The orange dashed line denotes the peak time of EUV late phase. f and g: light curves of the flare in 1−70 and 70−370 Å. The magenta and green dashed lines represent the background intensities, respectively.
