Overview of the event on 2023 May 8. (a) GOES 1−8 Å soft X-ray light curve (black) of the C3.1-class flare and the ASO−S/HXI count rate from combined total flux detectors (D92+D93+D94) in the 25−50 keV energy channel (orange) between 08:22 and 08:28 UT. (b) Radio dynamic spectrum observed by CSO/CBSm (110−300 MHz), Learmonth (80−110 MHz), and GERMANY-DLR (50−80 MHz), displaying various type III and type III-like (J, N) bursts followed by a type II burst. Both fundamental (F) and harmonic (H) emission lanes can be identified for the type N burst and type II burst.
