We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by AMPEL and ALeRCE (selected from the ZTF data stream). All observations were made on 2021 Jul 15 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 Si II 6355 velocity of -10,900 km/s.
(2) We measure an H-alpha velocity of -14,400 km/s.
(3) We measure an Si II 6355 velocity of -10,600 km/s.
