The historical light curve of this star exhibited an outburst in 1903, initially raising suspicions of a slow nova or FU Ori variable (Williams, 2005). However, subsequent spectroscopic observations confirmed its classification as a symbiotic star, with the detection of O VI lines (Bond & Kasliwal, 2012; Rodríguez-Flores et al., 2014).
