The distance and structure of L379
UBV and H-beta photometry has been carried out on 107 stars locatedwithin the more obscured region of the dark galactic cloud L379. Most ofthe measured stars are fainter than 10.0 m and their spectralclassification is not available in the literature. Spectral types werefound for 47 stars using movement along the reddening line coupled withthe assumption that all stars are on the main sequence. For each star,the extinction A(v) (mag) and the distance r(kpc) were derived, and fromthe A(v)-r graph, an attempt was made to determine the structure ofL379.
| UBV photometry in the vicinity of L379
UBV photometric sequence is presented for 102 stars in the vicinity ofL379, which was obtained for distance determinations of L379, anisolated dark cloud which has been identified as a source of bipolarmolecular flow. Of these stars, 76 are those with known MK spectraltypes. The available data were insufficient for an accurate distancedetermination of L379, and additional UBV photometry within the cloud isplanned.
