We report the classification of AT2019rra from spectroscopic observations with the Kast spectrograph on the 3 m Shane telescope at Lick Observatory. The optical spectra were obtained on 2019 October 8 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 AT2019rra can be found at:https://antares.noao.edu/alerts/data/260084901 .

Note: (1)
AT2019rra was also reported to TNS by ALeRCE as a candidate supernova, associated with galaxy SDSS J163839.41+334042.1 with a photo-z of 0.087. However, using the H-alpha emission line from the host galaxy in the Kast spectrum we derived a redshift of 0.037.
