Scientific paper

Results of UBVR photoelectric photometry for 32 stars in Rho Oph dark clouds (RSF 1 Oph) are presented. Mean magnitudes and colors are determined on the basis of 30-70 observations of 12 known variables in this region. The H-R diagram of the Rho Oph star aggregate is discussed. The main sequence dwarfs are present on the H-R diagram up to +8 m. The main sequence extension of 1 Oph is a least 11 mag. The RSF 1 Oph luminosity function is discussed and a deficit of stars in the range of +2 m to +5 m is found.
