Evolution of the pair of magnetic elements in ROI 7. From top to bottom row: time series of line-of-sight component (LOS) of magnetic field, B_LOS (panel a); field inclination relative to the LOS, γ (panel b); line-of-sight velocity, v_LOS (panel c); total linear polarization (LP_tot) (panel d); line core intensity I_LC normalized to the local continuum I_C (panel e), and Ca II H 397 nm intensity recorded by SuFI (panel f). The yellow contour encloses the large negative magnetic polarity patch and the black (panels a–c)/green (panels d–f) contour indicates the small positive polarity patch of the pair. The magenta dots outline the PIL between the two patches. Times at which the images were recorded are given in panel a.
