Strom et al. (1974) have conducted a search for infrared sources associated with Herbig-Haro objects. They found an infrared source, SGS 1, near HH 12, embedded in at least 20 visual mag of extinction in the NGC 1333 dark cloud. Various factors suggest the presence of an infrared reflection nebula. In the context of the present investigation, high spatial resolution observations in the infrared have provided the basis for the development of a consistent model for SGS which consists of a low-luminosity, cool star with an accretion disk tilted to the line of sight, and one observed reflection lobe caused by the illumination of material above one of the polar regions of the accretion disk. It is pointed out that this model is similar to that of the infrared reflection nebula GSS 30 in the Ophiuchus dark cloud.
