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.
