As part of the SOAR telescope preparation for the Astronomical Event Observatory Network (AEON), 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 ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680). The observations were performed on the night of 15 April 2019 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 arc second, resulting in a spectral resolution of 0.636 nm. Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
