We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by ALeRCE (selected from the ZTF data stream). All observations were made on 2022 Sep 06 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Notes
ZTF22abdjqlm| AT2022sio | 17:27:23.43 | +56:33:31.78 | 0.026 | II |
ZTF22abduiem| AT2022sme | 00:29:28.11 | +27:10:47.37 | 0.054 | I | (1)

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 detect an absorption feature at ~6200 A in the rest frame. Assuming this feature is Si II 6355, we measure a velocity of -6,500 km/s.
