We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by GOTO and the Zwicky Transient Facility (ZTF). Observations were made on 2026 July 24 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 the H-alpha P-Cygni minimum of -13,400 km/s.
(2) We measure H-alpha FWHM of 2100 km/s.
