Notes

Classified as an OH/IR star with a faint, highly circular, planetary nebula, as reported in Cohen et al. (2005) and Cohen et al. (2006). The central star exhibits characteristics of a long-period variable, with a period of 1486 ± 20 days, according to Chapman et al. (1995). Additionally, a possible connection with symbiotic stars is suggested based on the observations of a symbiotic-like outflow, as discussed in Frew et al. (2016).
