Andrew Howell, Curtis McCully, Estefania Padilla Gonzalez, Craig PellegrinoGlobal SN ProjectAGN0.045399Global SN ProjectOur spectrum shows galactic lines of narrow H and O III at z=0.045399, which is matched by the redshift of the host galaxy WISEA J175725.25+265028.4 (2014ApJS..210....9B, value from NED). The long-term variability in the lightcurve (ZTF) and nuclear nature of the transient indicate an AGN.2022TNSCR1275....1N
