The star displays significant nebular Hα emission, and its NIR and MIR properties suggest the presence of an obscured RGB (or possibly AGB) star. The OGLE-III light curve of [RP2006] 774 indicates low-amplitude semi-regular variability with a period of ∼40–80 days, which could be attributed to an RGB star (Miszalski et al., 2011). However, Reid (2014) did not consider the MIR SED steep enough for a symbiotic star and classified it as a YSO.
