SiebertNone tns_2019qiz_2019-09-25_15-10-53_Keck1_LRIS.flmObjectThe spectrum is very blue, peaking blueward of 3200 A in the rest frame. Superposed on the continuum are several emission features, including He II 4686 and Balmer lines. We measure a He II 4686 FWHM of 17,700 km/s, and a H-alpha FWHM of 13,200 km/s. Assuming AT2019qiz is at a distance of 65 Mpc, it currently has an absolute g-band magnitude of Mg ~ -17.5 mag. The ZTF light curve indicates that the TDE is young and still increasing in brightness.
