Identified as a symbiotic star candidate in the HASH Database of PNe (Parker et al., 2016), this suggestion is based on infrared colors. The spectrum reveals a red continuum, along with prominent Hα, [N II], and [S II] lines. Additionally, the star has been classified as a Mira variable according to Huemmerich & Bernhard (2012).
