AIA images for the triggering (a), eruptive (b), and restoration (c) stages of the breakout eruption. The arrows point to key features including the X-shaped structure and the subsequent transverse structure (red arrows in panels (a) and (b)), the low-lying, expanding arcade underneath the X-structure (orange arrow), two sidelobes (white arrows), and the northern and southern large-scale high-lying arcades (blue arrows). The S1–S6 dashed lines are slits for distance–time maps, with the starting point marked by a short dash. Images in panels (a) and (b) are radially enhanced to make off-limb, faint emission more visible.
