The animations described in "Direct Imaging of a Prolonged Plasma/Current Sheet and Quasiperiodic Magnetic Reconnection on the Sun"

Movie S1: Hα-0.4 Å animation and TD intensity plot along P1Q1 depict the rising structures, inflows, and outflows during prolonged, episodic magnetic reconnection. The animation runs from 16:14 to 18:00 UT. Its real-time duration is 25 s. 

 Movie S2: Hα-0.8 Å animation and TD intensity plot along P2Q2 display the rising structures, inflows, and outflows during magnetic reconnection. The animation runs from 16:14 to 18:00 UT. Its real-time duration is 25 s. 

Movie S3: AIA 131 Å animation  and TD intensity plot along P3Q3 depict inflows, outflows, and associated heating during magnetic reconnection. The animation runs from 16:14 to 18:00 UT. Its real-time duration is 17 s. 

Movie S4: AIA 131 Å animation and TD intensity plot along P4Q4 show recurrent brightening at the CS and associated heating during magnetic reconnection. The animation runs from 16:14 to 18:00 UT. Its real-time duration is 15 s. 

Movie S5: Photospheric TiO animation displays the evolution of sunspots at the base of the fan-spine topology. The TD intensity plot along the horizontal slit (east to west) depicts the motion of P2'. The animation runs from 16:14 to 18:00 UT. The second part of the animation shows the evolution of the photospheric magnetic field in HMI magnetograms  and AIA 304 Å channel images. The animation runs from 15:00 UT to 20:58 UT. Its real-time duration is 20 s. 

Movie S6: AIA 131 Å animation shows the intensity fluctuations at the CS (within the red box), changes in GOES soft X-ray flux, and associated heating during magnetic reconnection. The animation runs from 14:31:47 to 20:57:11 UT. Its real-time duration is 48 s.

Movie S7: AIA 131 Å animation shows long-term evolution of intensity fluctuations at the CS, recurrent flares/jets (GOES soft X-ray flux), and associated plasma heating during magnetic reconnection.  The animation runs from 4:03:18 to 23:48:30 UT. Its real-time duration is 66 s.
