1 GCVS Team P = 40d or 80d [P.Tempesti, IBVS N1291, 1977.]. Absorption spectrum with overlaying emissions of high excitation [R.E.Wilson, PASP 62, 14, 1950., R.E.Stencel, J.Sahade, ApJ 238, 929, 1980.]. Strong variable magnetic field [H.W.Babcock, ApJ Suppl 3, N30, 1958.]. Long period variations of light are observed. Radial velocities profiles and equivalent widths of lines vary with P = 470d [S.E.Smith, ApJ 237, 831, 1980.] (SB? [S.Smith, BAAS 12, N1, 341, 1980.]). Possibly is analogous to HM Sge [R.E.Stencel, J.Sahade, ApJ 238, 929, 1980.].
