Notes

A possible symbiotic classification was investigated, but it seems that the object is rather a young PN (Corradi & Schwarz, 1993). Bryce et al. (1997) detected fast-mO VIng jets from the central star. Clyne et al. (2015) reported that the position of the object in the diagnostic diagram is not consistent with the symbiotic classification. The object's position in the diagnostic diagram was reported to be inconsistent with symbiotic classification by Clyne et al. (2015). Further investigation by Miszalski et al. (2018) identified a binary nucleus with an orbital period of 18.15 days. The secondary component was suggested to be an M5V star, which rules out the symbiotic classification.
