The sunspot exhibits multiple structures, including a lightbridge and a region where Ca II 8662 {\\AA} line core is in emission. Correspondingly, the H$\\alpha$ line core image displays brightening in the emission region, with the spectral profiles showing elevated line cores. The stratification of the line-of-sight magnetic field is inferred through non-LTE multiline inversions of the Ca II 8662 {\\AA} line and the weak field approximation over the H$\\alpha$ line.
