Classified as a suspected symbiotic star by Allen (1984), this star displays an M1 continuum with H I and He I emission lines, as reported in Mikołajewska et al. (1997). An incorrect position is given by Belczyński et al. (2000) (no bright star at the prO VIded position). In Akras et al. (2019), the star is listed as a confirmed symbiotic system; however, the observations obtained up to now do not allow for a full confirmation of the symbiotic status.
