Observations of the J = 2→1 CO line have been made in the galactic source Mon R2. Observations of the 12CO and 13CO isotopes at 230 and 220 GHz indicate that the 13CO is optically thick with τ13 > 1.1. there is a close similarity between line intensities and spectral shapes in the 12CO J = 1→0 and 2→1 transitions.
