Notes

Sanduleak & Stephenson (1973) observed a stellar appearance and the presence of [O III] lines in the object. Subsequently, Allen & Swings (1976) detected [Ne III] lines. The infrared variability was studied by Feast et al. (1983), confirming the presence of a Mira in the system. Based on this, Whitelock (1987) classified the object as a symbiotic Mira.
