Notes

Noted as a possible symbiotic star already by Allen (1973), it was subsequently classified as a potential symbiotic star by Mikołajewska et al. (1997). Although its emission line spectrum bears resemblance to Be stars, the continuum slope suggests a G-type star.Hillier et al. (1998) proposed that the object is a P Cyg-type supergiant.
