========================

AT2019qiz was discovered in real-time alerts from the Zwicky Transient Facility [ZTF; @Bellm2019; @Masci2019; @Patterson2019], at coordinates RA$=$04:46:37.88, Dec$=-$10:13:34.90, and was given the survey designation ZTF19abzrhgq. It is coincident with the centre of the galaxy 2MASXJ04463790-1013349 (a.k.a. WISEAJ044637.88-101334.9). The transient was first identified by the ALeRCE broker, who reported it to the Transient Name Server on 2019-09-19 UT [@Forster2019]. It was also reported by the AMPEL broker a few days later. In subsequent nights the same transient was independently reported by the Asteroid Terrestrial impact Last Alert System [ATLAS; @Tonry2018] as ATLAS19vfr, by *Gaia* Science Alerts [@Hodgkin2013] as Gaia19eks, and by the Panoramic Survey Telescope And Rapid Response System (PanSTARRS) Survey for Transients [PSST; @Huber2015] as PS19gdd. The earliest detection is from ATLAS on 2019-09-04 UT.

We have been running the Classification Survey for Nuclear Transients with Liverpool and Lasair (C-SNAILS; @Nicholl2019csnails) to search for TDEs in the public ZTF alert stream. AT2019qiz passed our selection criteria (based on brightness and proximity to the centre of the host galaxy[^4]) on 2019-09-25 UT, and we triggered spectroscopy with the Liverpool Telescope. On the same day, @Siebert2019 publicly classified AT2019qiz as a TDE using spectroscopy from Keck I.
