We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by YSE and ALeRCE (selected from the ZTF data stream). All observations were made on 2021 Aug 08 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) Broad hydrogen features have emerged, so we now classify this as a SN II. We measure an H-alpha velocity of -8,900 km/s
(2) Broad hydrogen features have emerged, so we now classify this as a SN II. We measure an H-alpha velocity of -12,000 km/s
