Notes

The suggestion of a symbiotic nature for this star was made by Hodge & Wright (1970) due to light curve variations. However, this classification was rejected by Allen (1980) based on the observed low excitation in the spectrum. The star is also listed among RGB long-period variables in Spano et al. (2011).
