We report the following classification of AT2019oup, AT2019oxt, and AT2019ozf from spectroscopic observations with the Kast spectrograph on the 3 m Shane telescope at Lick Observatory. The optical spectra were obtained on 2019 September 5 UT. Targets were flagged and supplied by ANTARES (antares.noao.edu) and our customized filter as promising stellar explosion events. Classification and redshift determination were performed with astrodash (https://github.com/daniel-muthukrishna/astrodash).

Note: (1) Best match to SN 2007fb at 5.6 days. (2) If we fix the redshift to z = 0.154 (based on the host galaxy from SDSS), the fit results in a normal SN Ia, albeit with a worse fit;.(3) Redshift determined with the H-alpha emission line from the host galaxy. Best match to SN 1999em, SN 2004et, and SN 2005cs.
