Classified as a symbiotic candidate or [WR] central star of a planetary nebula in the HASH Database of PNe (Parker et al., 2016), the spectrum of this star displays Balmer lines in emission, along with He I, [O III], and faint He II. Jacoby et al. (2021) found no significant variability in the central star using Kepler/K2 data.
