AR 12720 as observed by the Solar Dynamics Observatory (SDO). Panels (a) to (c) show images in the 171 Å, 304 Å, and 1700 Å channels. Panel (d) shows the LoS magnetic field in the photosphere obtained with the HMI. The green rectangle shows the field of vision (FoV) of MiHI. The resolution of the HMI magnetogram was reduced to match the Atmospheric Imaging Assembly (AIA) plate scale.
