Individual Photoelectric UBV Observations of the Massive Early-Type Binary System V729 Cyg (Cyg OB2 No. 5)

Individual UBV photoelectric observations of the massive eclipsing binary system V729 Cyg, located in the stellar association Cyg OB2, are presented. The spread in the data points exceeds the measurement error. This is clearly the result of active physical processes in the system.
