1 GCVS Team B-V = +0.10, U-B = -0.95. SB (P = 0.1628d [A.Shafter, IAU Circ N3689, 1982.]). Spectrum description [M.D.Popowa, Eh.A.Vitrichenko, Pis'ma Astron. Zh. 3, N6, 271, 1977.; V.T.Doroshenko, V.M.Lyutyj, V.Yu. Terebizh, Pis'ma Astron. Zh. 3, N11, 510, 1977.]. Wide hydrogen emission lines. Long maxima and minima lasting for years are superimposed by rapid light variations by 1 - 2m in several days or fortnights and by 0.5m in dozens of seconds [M.D.Popowa, Eh.A.Vitrichenko, Astron. Zh. 55, 765, 1978.; V.T.Doroshenko, V.M.Lyutyj, V.Yu. Terebizh, Pis'ma Astron. Zh. 3, N11, 510, 1977.]. The source of soft X-rays [S.L.Mufson, W.Z.Wisniewski, R.S. McMillan, IAU Circ N3471, 1980.].
