The first panel shows the {\em Hinode} SP 6302\,\AA\, continuum maps constructed from Stokes $I$ spectra. Part of the field-of-view is not covered by the SP slit data. The images were clipped between 10k and 16k. The following panel displays the B$_{long}^{app}$ maps clipped at $\pm$ $80$\,Mx\,cm$^{-2}$ retrieved with the sp$\_$prep.pro code. This is followed by the {\em Hinode} Ca\,{\sc ii}\,H image (clipped to below 1500 counts) and the {\em IRIS} $2796$\,\AA\, band slitjaw image (clipped to below 200 counts). In the {\em IRIS} slitjaw images one can clearly see the {\em IRIS} slit position as a vertical dark strip. A thinner dark strip next to the slit position is due to reflections within the instrument. In all panels the contours are for $\pm$ B$_{long}^{app}$ $30$\,Mx\,cm$^{-2}$ shown with green and red colors denoting opposite polarity. The yellow contours are at levels of $60$\,Mx\,cm$^{-2}$ shown for both polarities. The contours for B$_{trans}^{app}$ $120$\,Mx\,cm$^{-2}$ are in blue. The FOV marked with a square in the last column shows the area displayed in Fig.2. The times labeled on the left refer to the recording time of the {\em IRIS} slitjaw images in the $2796$\AA\, band. For {\em Hinode} we chose the closest frames referring to this time (see also section 2 for explanation of the time frame).
