Scientific paper

The first photoelectric sequence for the magnitude differences of 215 close visual binaries in the Johnson UBV and Stromgren uvby systems have been established. In addition, the position angle and the separation of 140 stars were measured. Finally, for 134 stars, new photoelectric measurements of the combined integral brightness of both components in the UBV and Stromgren systems were made. The measurements were carried out using the area scanning technique.
