We report the following classifications of optical transients from spectroscopic observations with KOSMOS on the KPNO Mayall 4-m telescope. Targets were supplied by the ASAS-SN, ATLAS and Gaia. All observations were made on 2016 Dec 27 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 a Si II 6355 velocity of -11,100 km/s. (2) We measure a Si II 6355 velocity of -10,800 km/s. (3) We measure a Si II 6355 velocity of -11,900 km/s.
