We applied the Wilson-Devinney procedure to the light curve and the radial velocity curve obtained by us in 1978 and 1984, respectively, for a simultaneous solution and found a set of parameters that fit both curves. These are, mass ratio q = m2/m1 = 3.019 +/- 0.006, M1 = 0.39 Msolar, R1 = 0.75 Rsolar, M2 = 1.17 Msolar, R2 = 1.24 Rsolar. Both components are close to the main sequence. The over-contact degree of the common envelope is 19%.
