1 GCVS Team Extended shell of gas and dust. Emissions of [FeII], [NiII], [CrII], [SII], [OI], FeII. IR excess (1.6 - 20 mkm). P Cyg profiles of Balmer lines vary in the time scale of hours. Brightness varies from night to night by 0.1m and during a night by 0.03m, sometimes in correlation with spectral changes [J.P.Swings, R.Barbier, M.Klutz, A.Surdej, J.Surdej, AsAp 90, 116, 1980.]. Spectral studies [J.P.Swings, AsAp 26, N3, 443, 1973., A.R.Hyland, Proc ASA 2, N1, 14, 1971., F.Ciatti, S.D'Odorico, A.Mammano, AsAp 34, 181, 1974.].
