Notes

Listed as a symbiotic star candidate in the HASH Database of PNe (Parker et al., 2016), this star exhibits strong bipolar outflows. Classified as a young planetary nebula by Viironen et al. (2009), and positioned at the borderline between planetary nebulae and D-type symbiotic stars according to Corradi et al. (2010). The spectrum displays very strong Hα, with the absence of other lines.
