We report the following classifications of optical transients from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. Targets were supplied by PSST and ATLAS. All observations were made on 2017 Jan 3 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes: When the redshift is given to 2 decimal places, it is derived from the SN spectrum. Otherwise, the redshift is determined from the host galaxy.
