Overview of the solar flare on 2023 June 20. a: full-disk light curves from 16:41 UT to 17:30 UT recorded by GOES at 1–8 Å (red) and 0.5–4 Å (blue), and the local light curve integrated over the flare region measured by SDO/AIA at 131 Å. b: full-disk light curves between 16:56 UT and 17:15 UT in passbands of HXI 20–80 keV (magenta), KW 20–80 keV (green), and EOVSA 7.66 GHz (cyan). The context images are radio dynamic spectra observed by SWAVES (a) and EOVSA (b), respectively.
