Scientific paper

The Algol-type system S-Equ is observed yielding UBV photoelectric data which are examined in terms of the orbit eccentricity of the system. The observational data are found to contradict the orbit eccentricity, while the mass ratio confirms previous calculations. It is suggested that S Equ is a triple system based on the hypothesis that a third light source comparable to the cooler component can account for the total flux of the system.
