Similar to Figure 2, but from 03:08 UT to 03:19 UT in panels (A)–(F). The black arrows and the cyan circles in panels (A) and (B) denote the horizontal motion front. The white and black arrows in panel (C)–(E) point out the bright footpoints. The red circle marks the bright plasma. The slit position for the time–distance plot in Figures 5(B1)–(B4) is shown by the dashed cyan arrows in panels (B), (C), (E), and (F). NVST Hα line wing images (panels (C)) and the AIA 1600 Å and 171 Å (panels (E) and (F)) are shown in the animation.
