Cutout on the sunspot of AR13468. Left column: PHI/HRT and EUI/HRI observations re-projected on the SST/CRISP frame. Right column: SST/CRISP observations for the H α 6563 Å continuum (wide-band filter, top), −0.8 Å blue wing (middle) and line core (bottom). The white rectangle depicts the sub-region selected for the photospheric motion analysis. The intensities are colour-plotted on a logarithmic scale (only the values between the 0.1% ad 99.9% percentiles are mapped). The artificial slits traced in white colour are used later for the coronal oscillation analysis.
