In Merrill & Burwell (1950), the symbiotic nature of the object was suspected based on the presence of [Fe VII] emission lines. Subsequently, in Munari (1992), a symbiotic nova-type outburst was suggested, but later investigations indicated behavior similar to Z And (Esipov et al., 2000; Tatarnikova et al., 2009; Kolotilov et al., 2012). In Mikołajewska et al. (1997), an earlier spectral type (M0) was given, but it is worth noting that the object might have been in outburst during the observations. The long-term light curve is presented in Siviero et al. (2007).
