Evolution of the magnetic structures at the footpoints of the recurrent jets. Panel (a): SO/PHI-HRT B_LOS map overlaid with SO/EUI-HRI 174 Å images of the entire AR. The red square outlines the subfield (in the subsequent panels) where the recurrent jets occur. Panel (b): SO/EUI-HRI 174 Å image cropped to the red-boxed region in (a). Panel (c1): Co-spatial SO/PHI-HRT magnetogram of the same subfield. Panels (c2)–(c4): Temporal sequence of magnetograms, showing the evolution of the magnetic field in the jet footpoint regions. The green and red circles enclose the northern and southern jets, respectively. These regions were chosen to remain as isolated as possible from surrounding flux concentrations. Panels (d) and (e): Time series of the magnetic flux calculated within the green and red circles, respectively, illustrating the flux changes in the two jet footpoint regions.
