VdB 109 is a reflection nebula in the constellation of the Ophiuchus. It is located in the southern part of the constellation, north of the Rho Ophiuchi Complex, a large molecular cloud where stellar formation processes are active. VdB 109 is a weak nebula veil extending in front of the star HD 150416, a magnitude 4.93 giant of spectral class G8III. The parallax measurements of this star indicate a distance of approximately 120 parsec (391 light years) from the solar system. This distance is compatible with that of the Cloud of Rho Ophiuchi and the dark clouds associated with it, such as the long filament B41 , to which the IC 4601 reflection nebula is bound. This particular cloud is located within a few decades of parsecs from the Scorpius OB2 association, linked to the Scorpius-Centaurus Association.
