ROI A: a region with complex loop-like structures, observed in the 5 May scan, with clear opposite polarity longitudinal and transverse components present in every frame. Upper panels: first row showing the Stokes I normalized continuum, with subsequent rows showing, in descending order, as retrieved from S1 inversions: v_LOS, B, γ, α, and αB. Maps of B saturate at 500 G so weaker fields are more easily visible. The columns show a selection of subsequent frames. Bottom panels: temporal evolution of the following quantities are shown for the pixel whose spatial and temporal location in ROI A is highlighted with a solid magenta square outline above (i.e. the pixels A.1–3): αB, γ (left) and v_LOS, I/I_c (right) as derived from S1 inversions. The horizontal dashed, grey lines indicate the position of 90° on the left panel and 0 km s⁻¹ on the right panel. The vertical dotted, red lines are a visual aid for the time-stamps of the start and end-point of the left panel.
