P var. There is an additional periodic term in the elements: -0.00627d*sin (2.221deg*E + 15deg). The ratio of Min II depth to Min I depth is 0.78. There is secular deepening of both minima. The depth of Min I increases by 0.016m per year. The range of light variation in the Table is given for 1979.0 (Min II 8.69). Orbital inclination is increasing by 0.5deg per year [J.A.Eaton, IBVS N1614, 1979.] due to orbital precession caused by a third body. Spectrum description [A.Mammano, R.Margoni, R.Stagni, AsAp 59, N1, 9, 1977.].
