Standardized photoelectric magnitudes and color indices of 23 components of 17 visual binaries are presented.

A time of minimum light for VV Orionis has been determined photographically using techniques developed by Jeong. The observed time of minimum light shows that VV Ori exhibits a constant orbital period. The O-C computed with the light elements given by Eaton is found to be − 0 d , 0070. An attempt to correct for night-to-night shifts for plates taken on three nights in February and March 1975, was unsuccessful and thus the complete light curve initially planned was not obtained.

An attempt has been made to re-evaluate the photospheric iron abundance by comparing computed, theoretical line profiles with observations. Our resulting abundance is found to be in good agreement with that of Garz and Kock (1969), when the logarithmic abundance of iron is taken to be 7.5.
