Overlay of the 3.6 µm Spitzer/IRAC image (contours) on the 2.2 µm LBT/SOUL image from Massi et al. (2023). The contour levels range from 30 to 430 in steps of 50 MJy/sterad. The dashed ellipse denotes the full width at half power of the 1.4 mm continuum emission mapped with ALMA by Cesaroni et al. (2025). The cross marks the expected position of the protostar.
