Notes

Suspected by Munari et al. (1999), the spectrum of this object reveals the continuum of a carbon giant, a hot blue continuum, and emission lines of H I. No highly ionized emission lines were detected. Belczyński et al. (2000) suggested that the object might be a single pulsating star pulsating with a period of 342 days (Dahlmark, 1994). The star was detected in a possible outburst by Munari et al. (1999). On the other hand, Sobotka et al. (2003) claimed that the brightening was not caused by an outburst but rather by Mira-like pulsations.
