The presence of [Fe VII] lines was reported by Merrill & Burwell (1950), and the possible symbiotic classification was suggested by Wackerling (1970). Emission lines of He I, He II, [Ca VII], [Fe VII], and O VI were reported by Stenholm & Acker (1987). Despite considerations as a Mira variable, subsequent observations, as noted in Gromadzki et al. (2009), did not confirm this classification.
