[en] An extensive area of the Ophiuchus dark cloud has been mapped at far-infrared (40--250 μ) wavelengths with high angular resolution (1') using the 102 cm balloon-borne telescope. Three sources were detected and resolved. Two of the sources were identified with strong 2 μ sources that were also associated with radio continuum emission. The far-infrared flux is consistent with radiation from dust heated by an early B star. Previous 2 μ observations have indicated the presence of a large number of early B stars embedded in the dark cloud; the far-infrared observations indicate, however, that although some early B stars are in the dark cloud, most of 2 μ sources are either behind the cloud or are stars not on the main sequence
