H_α observations at the line center of 6563 Å from NVST showing the vortex motion on both sides of the prominence and its resulting effects. Along the prominence, as depicted in Panels (a-f), we identify several vortices at different positions, which are highlighted using white circles to demonstrate their diverse rotating directions. To determine the rotating directions, each selected vortex is magnified two times at the bottom of Panels (a-d), and the movements of brightening features are tracked as shown by white arrows. Furthermore, in Panel (e), the vortices from Panels (a-d) are superimposed on the image at 08:31 to illustrate a sequential vortex process. Finally, Panel (f) displays the redistribution of prominence material, indicated by two arrows pointing in opposite directions. An animation of this figure is available online.
