Panels (a), (e), and (i): Evolution of the wFR from an observational perspective at simulation times 0, 7, and 15, respectively. Panel (b), (f), and (j): SDO/AIA 304 Å images capturing the filament eruption at 06:18, 06:25, and 06:33 UT, respectively. The white and black lines delineate the trajectory of the filament at the respective times. Panel (c), (g), and (k): Photospheric twist distribution overlaid with red contours of QSLs (log Q = 7) at the same simulation times as panels a, e, and i, respectively. Panels (d), (h), and (l): SDO/AIA 1600 Å images illustrating the evolution of flare ribbons at the same observation times as panels b, f, and j, respectively. In panel l, the spatial distributions of tail-like ribbon and a head-like ribbon are demarcated by yellow circles and blue squares, respectively.
