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 and ATLAS. All observations were made on 2017 Oct 28 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

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 Si II 6355 velocity of -10,800 km/s.
(2) We find weak CII 6580 line in the spectrum.
