The symbiotic classification was initially suggested by Webster (1966) based on the spectrum. However, in Gutiérrez-Moreno et al. (1987), it was proposed that the object is a young planetary nebula, and its spectrum is not consistent with a symbiotic classification. The non-detection of X-ray emission reported by Stute & Luna (2011) was considered as a factor favoring a young planetary nebula classification or a symbiotic star in hibernation. In Pereira et al. (2010), the central binary was analyzed, and it was claimed that one component is an A3-4 II star.
