Notes

Suspected in Vaidis (1988). The spectrum reported by Sanduleak & Stephenson (1973) showed OB-like continuum in the ultraviolet and TiO bands with no emission lines in the blue-green region. In Pereira et al. (2003), only Hα, Hβ, and Hγ emission lines were detected, leading to the conclusion that the spectrum is similar to VV Cep. They suggested M1 I classification for the object. Classified as a Mira variable in SIMBAD (Wenger et al., 2000) with reference to GCVS, but there the star is classified as an SRa variable.
