Notes

Identified as an X-ray source in M31. Noticed as a possible candidate remnant of the supernova of 1885 (Di Stefano et al., 2004). This identification had already been examined and rejected by Kaaret (2002).  In SIMBAD both objects are considered as one. Chiosi et al. (2014) suspected its symbiotic nature. They found an object with colors that may indicate symbiotic in the error circle of this X-ray source.
