(a)−(e): HRI_EUV 174 Å sequence images depicting the evolution process of the fan-spine-like topology. In panel b, the emerged and ambient open field are outlined by dashed green and white lines, respectively. The yellow arrows point to the X point of reconnection between the emerging field and the surrounding open magnetic field in panel c. The pink arrows denote the plasma blobs in current sheet 1 (d). Panel (e): Fan surface and spine of the fan-spine-like structure are outlined by dashed red lines, and the dashed green and white lines outline the closed magnetic flux under the fan dome and the open flux above the fan dome, respectively. Panel (f): Time-distance diagram along the direction of the white line in panel c. An animation of the whole evolution process of the fan-spine system is available from 22:00 UT to 22:58 UT. The duration of the animation is 9 s.
