Abstract

UBV photometry of RS CVn-type eclipsing binary system ER Vulpeculae has been presented. The period comes out to be 0 d. 698093. The average depths of primary and secondary minima are, respectively, 0 m. 21 and 0 m. 12. The colours at various phases have been given. A dip is seen around phase 0 p. 73 as was seen in the observations of Arevaloet al. (1988). Large scatter is present in the observations as noticed earlier, and may be due to activity of the components.
