Cartoon illustrating a possible connection between a radio dimming and filament eruption. (a) Evolution of the normalized flux at 324 MHz on 2024 March 17, representing both the sun-as-a-star flux curves in Figure 3 and the flux variations in the right column of Figure 6. In (a), the blue line marks the pre-eruption level. (b)–(f) The filament eruption process and the changes of the d_{los, τ = 1} (indicated by the red arrows) and the obscuration area (A). The times t₀–t₄ correspond to the times shown in (a). In (b)–(f), “cor” and “fil” represent “corona” and “filament”, respectively.
