We report the following the classifications of astrophysical transients from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2024 June 13 UT. The targets were supplied by ATLAS, ZTF, and YSE, and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The 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.
