In 1891 - 1964 light variations in the range 14.2m - 15.5m with deep minima to 18m; the minima are satisfied by the elements given in the Table; D = 0.1p; spectral type M [F.M.Stienon, M.R.Chartrand, C.Y. Shao, AJ 79, 47, 1974.]. In 1964 - the outburst up to 12.1m. Then gradual brightness decrease superimposed by periodical variations with an amplitude near 1m. Light minima as before are satisfied by the elements given in the Table but the character of eclipses changed (probably because of appearance of a dense envelope ejected by one of the components of the system). After the outburst high excitation emission spectrum with IR excess is observed similar to the spectrum of symbiotic variables. |
