SO/PHI−SO/EUI aligned FOVs. The SO/PHI LOS magnetogram of the first full dataset of 1024″ × 1024″ is overlaid on the co-aligned HRI_Lya (left) and HRI_EUV (right). The SO/PHI magnetogram was made partially transparent to make the correlated features between the two instruments more visible. The dashed box in the middle of the SO/PHI FOV is the observed region in the other seven SO/PHI datasets to which the aligned HRI_EUV images were cropped. Solar north is up and solar west is to the right.
