Temporal evolution of Region 2 observed by EUI and the SXR and HXR emission of the flare. Panels (a)–(d) show the evolution of Region 2, while panel (e) displays the GOES 1–8 Å SXR light curve together with the STIX 4–10 keV and 25–50 keV HXR light curves. Details of the HXR data processing are described in Tan et al. (2025a). The grey shaded region indicates the EUI observing time span. The vertical dashed lines mark the times corresponding to panels (a)–(d).
