Overview of type-I burst chains on 2024 February 14. (a) SXR/HXR light curves recorded by GOES, MSS-1, and HXI during 06:45–07:55 UT; two solar flares are marked. (b) Dynamic spectrum of CBSm between 07:00 and 07:20 UT. Two horizontal lines outline the frequency range of solar meterwave bursts (1–7). (c) Dynamic spectrum of MUSER-L. The white dashed line marks the frequency at 238 MHz. (d) Dynamic spectrum of polarization measured by DART. The dashed line marks the frequency at 238 MHz.
