Overview of the solar flare and coronal loop on 2022 September 29. (a): light curves integrated over the entire Sun at GOES 1−8 Å (black) and 0.5−4 Å (blue), and STIX 4−10 keV (red). The blue vertical lines mark two peaks of the solar flare in the GOES 0.5−4 Å flux. (b) and (c): snapshots with a FOV of ∼330″×330″ in passbands of SUTRI 465 Å and AIA 94 Å. The magenta curve outlines a full loop profile, the gold arrow indicates the flare site, and the black line marks the solar limb. The whole evolution is shown in a movie available online.
