An elliptical Hα nebula is observed around [RP2006] 264. The very red color and very high MIR luminosity suggest an obscured RGB or AGB star with significant variability in the OGLE-III I-band lightcurve. The combination of the nebula and obscured star makes [RP2006] 264 an excellent symbiotic star candidate (Miszalski et al., 2011). It was also suspected in Reid (2014).
