Their reported spectrum, and our own data obtained over the following nights, showed broad He II and Balmer emission lines superposed on a very blue continuum, characteristic of UV-optical TDEs. Follow-up observations from other groups showed that the source was rising in the UV [@Zhang2019], but was not initially detected in X-rays [@Auchettl2019]. Radio observations with the Australia Telescope Compact Array (ATCA) revealed rising radio emission, reaching 2.6mJy at 21.2GHz on 2019-12-02 [@OBrien2019], placing AT2019qiz among the handful of TDEs detected at radio wavelengths.

The spectroscopic redshift of AT2019qiz, as listed for the host galaxy in the NASA Extragalactic Database (NED) and measured from narrow absorption lines in the TDE spectrum, is $z=0.01513$. This corresponds to a distance of 65.6Mpc, assuming a flat cosmology with $H_0=70$kms$^{-1}$Mpc$^{-1}$ and $\Omega_\Lambda=0.7$. This makes AT2019qiz the most nearby TDE discovered to date.

AT2019qiz was included in the sample of 17 TDEs from ZTF studied by @vanVelzen2020. Their study focused primarily on the photometric evolution around peak,
