We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by The Young Supernova Experiment, ZTF and Gaia. All observations were made on 2021 Nov 8 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 H-alpha absorption velocity of -11,200 km/s.
(2) We measure a Si II 6355 velocity of -10,700 km/s.
(3) We measure a Si II 6355 velocity of -11,100 km/s.
