X-ray Bright Nuclear Transient with Bowen Fluorescence Lines

We report follow-up observations of bright, nuclear transient AT2019pev/ZTF19abvgxrq/Gaia19eby. Our spectroscopic follow-up campaign, initiated on 2019 September 08 with the Palomar 60in SEDM, and most recently with the Discovery Channel Telescope DeVeny Spectrograph on 2019 September 23, shows the presence of strong narrow-line emission consistent with a star-forming galaxy at z=0.097, a blue continuum, and a resolved He II 4786+[NIII] line complex and relatively narrow broad Balmer lines (FWHM 1300 km/s) characteristic of the new class of flaring accreting SMBHs like AT2018bgt (Trakhtenbrot et al. 2019).
