Notes

Classified as a possible symbiotic bipolar outflow by Phillips & Ramos-Larios (2008), this object had previously been classified as a young supernova remnant, young stellar object, luminous blue variable, H II region, and a planetary nebula (refer to the references in Phillips & Ramos-Larios (2008) for details on the previous classifications).
