We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ZTF (both self-reported and as reported by ALeRCE). All observations were made on 2021 Jan 6 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) Blue spectrum, with an indication of a P-Cygni H-alpha component at -7,000 km/s. The long rise (~ 1 month) and the luminosity (M_g = -19 mag) indicates some interaction.
