Notes

Allen (1978) reported a high excitation level indicated by the presence of O VI lines, while noting the absence of a TiO absorption spectrum. Subsequently, Gutiérrez-Moreno et al. (1997) discussed UV and optical observations of the object. Tomov et al. (2000) reported the discovery of bipolar jets that emerged during an outburst. The detailed analysis of this outburst is presented in Munari et al. (2005). A second outburst was detected in 2012, as reported in Munari et al. (2012), Munari et al. (2012), and Tomov & Tomova (2013).
