1 GCVS Team Before the outburst in 1964 the brightness changed between 15.0m and 17.5m pg [W.J.Miller, Ric Astr 7, N6, 1967.], the spectral type was late Me alpha [J.J.Nassau, D.M.Cameron, ApJ 119, 175, 1954.]. In the 1964 - 67 the brightness increased from 16.0m to 11.2m B. In 1967 - 69 the brightness steadily increased to 10.05m B, being constant in V system (10.5m). In the infrared it changes in the limits 6.9 - 8.4 J, 4.7 - 5.8 K with the period 470d [P.M.Harvey, ApJ 188, 95, 1974., O.G.Taranova, B.F.Yudin, Pis'ma Astron. Zh.6, N8, 495, 1980.]. High excitation emission spectrum with strong IR excess resembles that of symbiotic variables [W.A.Feibelman, ApJ 258, 548, 1982.]. X-ray and radio source.
