The star underwent a transformation in its spectral appearance, transitioning from a low-excitation emission line object to that of a symbiotic star, likely due to the optical thinning of the nebula (Remillard et al., 1992). Subsequent analysis of archival observations in Iłkiewicz et al. (2019) supports the classification of the object as a symbiotic recurrent nova.
