Using the APEX 12-m telescope, we mapped the line emission from the J=2-1 rotational transition of two CO isotopologues, 13CO and C18O, over a 4' x 4' region around Orion B9/SMM 3. Both the 13CO and C18O lines exhibit two well separated velocity components at about 1.3 and 8.7 km/s. The emission of both CO isotopologues is more widely distributed than the submillimetre dust continuum emission as probed by LABOCA.
