2 GCVS Team The depth of Min I 1.12m - 2.21m. D = 0.052P - 0.086P, d ~0.03P. P var? [O.E.Mandel', Perem. Zvezdy 15, 474, 1965., J.L.Africano, R.E.Nather, J.Patterson, E.L.Robinson, B.Warner, PASP 90, 568, 1978., J.L.Africano, R.W.Quiglev, T.J. Schneeberger, S.P.Worden, BAAS 11, N2, 433, 1979.]. Strong fluctuations of light outside eclipses. the lower the brightness outside the eclipse, the deeper the Min. In J, K light Min II of 0.16m J depth was found at the phase 0.50P [A.J.Longmore, T.J.Lee, D.A.Allen, D.J.Adams, MN 195, 825, 1981.]. Flat spectrum of the accretion disc with emission lines.
