Notes

Suggested to be a probable supernova in AKARI J1006572-474345 (Kiyota et al., 2017), further investigations revealed a spectrum resembling a foreground M-type star, possibly a nova or symbiotic star in outburst (Fraser et al., 2017). They asserted that the extended source is not a galaxy but a potential nebula. Subsequent confirmation of the M-type spectrum was reported (Morrell et al., 2017). The object is classified as a confirmed symbiotic star in the ASAS-SN database (Jayasinghe et al., 2019).
