Notes

Reid & Parker (2006) classified the star as a possible symbiotic star. Later, Reid & Parker (2012) classified the star as B giant. Miszalski et al. (2011) classified the object as HII region and according to their analysis, VMC and SAGE data are consistent with the dusty environment. Finally, Reid (2014) classified the object as an emission line star.
