Time series of the occurrence of jets in the prominence identified by regions where M_A > 1 at time = 671.53, 680.12, and 704.16 s. Panels (A–C) show the zoomed images of Panels (D–F) and the occurrence of jets, here essentially flowing upwards. Panels (G–L) show the time evolution of current density (|J_z|) and magnetic field (|B_plane|) for zoomed regions where the jets emerge. Both the current sheets and subsequent magnetic islands responsible for the jets are clearly visible.
