(a1)–(a6) Initiation of Jet-3 and associated coronal dimming expansion near the N-hook region (SDO/AIA 171 Å images enhanced by MGN code). Blue and green circles in (a2), (a3), (a5), and (a6) mark the footpoints of the coronal side arcades and the HFR before and after reconfiguration, respectively. Panels (a3) and (a6) illustrate the proposed magnetic topology reconfiguration between the erupting HFR leg (red) and ambient coronal side arcades (cyan), yielding a newly formed side arcade (purple). White arrows in (a4)–(a6) indicate spicule-like subjets nested within Jet-3; green twin arrows in (a5) mark moving blobs. (b1)–(b3) AIA 1600 Å images showing N-hook evolution, overlaid with contours of the expanding coronal dimming (purple) and Jet-3 region (blue) derived from the 171 Å channel. (c1)–(c3) Multiwavelength time–distance diagrams of Jet-3, sliced along the red dashed path in (a4). The FOV of (a1)–(a6) and (b1)–(b3) is denoted by the white rectangle in Figure 3(a9). A 2.7 s animation using AIA 171, 304, 1600, and 94 Å passbands shows reconnection Jet-3 from 17:00:11–18:01:55 UT.
