We report the classification of AT2019ugu and AT2019ugv from spectroscopic observations with the Kast spectrograph on the 3 m Shane telescope at Lick Observatory. The optical spectra were obtained on 2019 November 6 UT. Targets were flagged and supplied by ANTARES (antares.noao.edu) and our customized filter as promising stellar explosion events. Classification was performed with DASH (Muthukrishna et al. 2019, arXiv:1903.02557). The light curve of AT2019ugu and AT2019ugv can be found at: https://antares.noao.edu/alerts/data/321743884 and https://antares.noao.edu/alerts/data/308491448 , respectively.
