SVS 12 is an embedded infrared source which is the probable exciting star for HH 12. The source has a “class I” IRAS spectrum and about 20 L© luminosity. Differential reddening between the star (J-K ≥ 6 mag) and the adjacent infrared reflection nebula (J-K= 3 mag) suggests the presence of dense circumstellar material (Stapelfeldt et al. 1991). SVS 12 was observed with the OVRO interferometer in the 13CO 1-0 and CS 2-1 lines and associated continuum, and at the CSO with a bolometer and in the CS 5-4 and CS 7-6 lines.
