Temporal evolution of three PMJs whose positions within the penumbra are indicated in Fig. 1: PMJ 1 (top), PMJ 2 (middle), and PMJ 3 (bottom). Right: for each case the panels show, from top to bottom, maps of total linear polarization (TLP), total circular polarization (TCP), and net circular polarization (NCP). Contours enclose the PMJ area. Time runs from left to right with 17 s cadence. Left: evolution of the average TLP, TCP, and NCP in the microjet area. The vertical dotted lines correspond to the frames before, maximum, and after.
