Multiwavelength imaging of a solar active region. The leftmost panels show an extended view of the target, while the ones on the right show a closer look at the center. Panel A: AIA 304 Å intensity in logarithmic scale (18:48:53 UTC); panel B: SST/CRISP λ8542 Å core (18:48:41 UTC); panel C: ALMA brightness temperature at 3 mm (18:48:53 UTC); panel D: HMI LOS magnetogram clipped at ±1 kG (white/black, 18:49:30 UTC); panel E: composite of total linear polarization (red) and total circular polarization (blue) in λ6173 (18:48:53 UTC); panel F: TLP in λ8542 (18:48:41 UTC). Solid circle and dashed square show the ALMA and SST fields. The cyan contours correspond to T_b [3 mm] = 9 kK.
