Notes

Listed as a confirmed symbiotic binary in SIMBAD (Wenger et al., 2000), with the reference to Henize (1976). However, Henize (1976) suggested a possible VV Cephei type classification. Pereira et al. (2003) supported such classification as they classified the object as an M2 I star. The confirmation of an Ia class star through absolute infrared magnitude measurements is reported by Munari et al. (2021).
