Scientific paper

New photoelectric observations of ER Ori in B and V were obtained in 1980 - 81. An extensive search for a reliable mass ratio q was carried out using the Wilson and Devinney method. Three solutions in different modes (mode 2, 4, and 5 respectively) were secured with almost the same Σ (the sum of square deviations). However, the values of (Ω-Ωin)/Ω are all smaller than 0.005 for the three solutions. This means that ER Ori should be an almost contact system.
