Notes

This highly reddened object, located in a region with faint and diffuse HII emission, exhibits distinct characteristics of a symbiotic star. The spectrum reveals a red giant continuum marked by prominent TiO bands, an exceptionally strong Hα line, multiple high-excitation emission lines, and the presence of the Raman feature. Based on its 2MASS colors, it is suggested that the object should be classified as a D-type symbiotic star (Rodríguez-Flores et al., 2014).
