We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ASAS-SN, ATLAS and Gaia. All observations were made on 2017 July 29 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. (1) We measure an H alpha velocity of -5,600 km/s. (2) We measure an Si II 6355 velocity of -13,900 km/s. (3) We measure an Si II 6355 velocity of -10,200 km/s.
