The spectrum shows narrow Balmer emission lines (FWHM ~1200 km/s), He I, He II and [O III]. The reported redshift was measured from these features. Applying the distance inferred from this redshift, we obtain a current absolute magnitude of M_g ~ -21.5 mag. The spectrum resembles a SLSN-II in some ways, but the presence of [O III] and He II, together with the small offset from the nucleus, instead suggest an AGN classification. In addition, the host galaxy has a history of optical variability in the PS1 DR2 catalog (though the amplitude of variability is lower than the current transient/outburst) and has been previously classified as a likely QSO (p > 95%) by Bailer-Jones et al. (2019; MNRAS, 490, 5615). More details in ATel #13970
