Notes

According to Miszalski et al. (2013), there might be a very weak detection of O VI 6825, but the absence of [Fe VII] emission lines makes its presence unlikely. The OGLE-IV light curve indicates low-amplitude semi-regular pulsations of the red giant superimposed on longer-term changes occurring over 400–500 days, possibly attributed to orbital motion.
