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, ATLAS, and ZTF. All observations were made on 2022 March 01 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 6355 II velocity of -9,300 km/s. (2) We measure an Si 6355 II velocity of -10,300 km/s. (3) Blue hot continuum with flash ionisation features of He II 4686 and blended C III 4648/ N III 4640.
