We report the following supernova classifications. The targets were supplied by the Zwicky Transient Facility (https://www.ztf.caltech.edu/; Kulkarni et al. 2018, ATel 11266) data stream processed through the Lasair broker (http://lasair.roe.ac.uk/), and by the All Sky Automated Survey for SuperNovae ASAS-SN (see Shappee et al. 2014, ApJ, 788, 48 and http://www.astronomy.ohio-state.edu/ assassin/index.shtml). The observations were performed on the night of 2019 April 14 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 0.6 nm. Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and Gelato (Harutyunyan et al., 2008, A&A, 488, 383).
