Classified as a symbiotic star candidate in the HASH Database of PNe (Parker et al., 2016), likely based on the study by Allen & Glass (1974). Initially considered as a potential planetary nebula (Perek, 1963). In 1983, infrared photometric variability was analyzed alongside other symbiotic objects, with no significant changes detected (Feast et al., 1983). Subsequent observations of Stenholm & Acker (1987) failed to identify an emission-line star, indicating the presence of an M giant only.
