Panel (a): Direction in which plasma outflow is ejected to its highest position (white arrow, slice 1). Slice 2 is along the direction of the eruption of filament 1 at the side of the fan-spine structure. Panels (b)−(c): HRI_EUV images overlaid on the FSI₁₇₄ images and FSI₃₀₄ running-difference images, showing the location of the fan-spine-like structure. The white arrows illustrate the plasma ejection material propagating along the closed magnetic field lines in panels (c2)−(c3). Panels (d)−(e): Time−distance intensity diagrams of HRI_EUV 174 Å plotted along slices 1 and 2 in panel a. The yellow curve represents the EUI 174 Å light curve, which is calculated within the dashed yellow box in panel a from 22:00 UT to 22:57 UT.
