1 GCVS Team In the region of the nebula IC 5070. SB (P = 0.25d [M.F.Walker, M.Bell, BAAS 12, N1, 63, 1980.]). Rapid small variations near maximum of brightness (B-V = +0.25) are superimposed sometimes by deep minima lasting for some hundreds days [D.Ya.Martynov, P.N.Kholopov, Perem. Zvezdy 11, N3, 222, 1957.]. Soft X-ray source [F.A.Cordova, K.A.Jensen, J.J.Nugent, MN 196, 1, 1981.]. Spectrum description [G.H.Herbig, ApJ 128, 259, 1958., M.F.Walker, M.Bell, BAAS 12, N1, 63, 1980.].
