Notes

This object is classified as a symbiotic star candidate in the HASH Database of PNe (Parker et al., 2016). It has been suggested as a possible Mira variable (Samus´ et al., 2017) and long-period variable (Mowlavi et al., 2018). The spectrum of this system reveals a red continuum and the presence of Hα emission.
