Notes

Included in the list of symbiotic candidates by Vaidis (1988), likely due to Gaposchkin (1957) mentioning the object as a symbiotic star as noted by Garcia (1986). However, it is identified as a VV Cephei type star (Cowley, 1969). The presence of a red supergiant with a B-type companion was subsequently confirmed by Neugent et al. (2018).
