| Abstract: | UBV photometry of RS CVn-type eclipsing binary system ER Vulpeculae has been presented. The period comes out to be 0.d698093. The average depths of primary and secondary minima are, respectively, 0.m21 and 0.m12. The colours at various phases have been given. A dip is seen around phase 0.p73 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. |
