We report the following supernova classifications. The targets were supplied by supplied by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680). The observations were performed on the night of 2019 January 17 at the 4.1-m SOAR Telescope equipped with the Goodman High Throughput Spectrograph using the 400 lines/mm grating, and a slit width of 1.0 arc second, resulting in a spectral coverage from 380 nm to 775 nm with a resolution of 0.636 nm. Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
