Dynamic spectrum of the type II burst observed on 2024 August 5 with the e-CALLISTO radio spectrometer in Greenland. The faint emission starting from ≈100 MHz at ≈13:32 UT (indicated by the red color arrow mark) and drifting slowly toward lower frequencies, with last appearance near ≈35 MHz at ≈13:41 UT, is the fundamental component of the type II burst mentioned in the main text.
