Panels a)−c): HMI LOS magnetogram, AIA 131 Å image, and SJI of 1400 Å showing the first fan-spine structure earlier on 17 November 2013. The yellow dashed circles in panels a) and c) delineate the bright ribbon while the blue dashed circles denote the secondary fan-spine structure covered by the dome displayed in Fig. 6. The green squares outline the FOV of panels d)−f). Panels d)−f): extended SJIs of 1400 Å exhibiting the secondary fan-spine structure. The black triangles track the material’s flowing toward the southeast. The full temporal evolution of the 1400 Å and 131 Å images is available as a movie (7.mp4) online.
