The light curve is characterized by outbursts up to 4m with intervals of 10 - 20 years. In the intervals cyclic variations are observed with the mean period of 632d and variations with cycles of several days and Delta(m) ~ 0.1m - 0.5m. The spectrum is symbiotic, with features of a late M giant, narrow low-excitation emission lines (Bleq) and forbidden lines characteristic of highly excited nebulae. |
