Three-colour stacked image of B207. The blue, green, and red colours represent the V, R, and I bands, respectively. The protostar, IRAS 04016+2610, at RA = 4^h4^m43.071^s, Dec = + 26°18′56.39″ is forming at a distance of about 8400 au west of the core, marked by the red arrow. A sharp boundary is seen towards the outer rim of the cloud to the east. A less dense region of material, appearing as a hole, is located towards the immediate west of the protostar.
