1 Otero, Sebastian Alberto VSP Note: 13.70 Vmag. companion 9" to the NNE.
2 Renz, Wolfgang Outbursts in 1936 and 1998 were ZAND-like and not NB:-like outbursts. The given elements are for the mira star component.
3 GCVS Team VB A (B 14.0m, 8", 190deg). Light variations of the Mira type variable are superimposed by the outburst of the probable nova which occured near JD2428400 (1936) with the consequent slow light decrease. Combined spectrum.
