We report the classification of astrophysical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2026 November 7 UT. The targets were supplied by ATLAS, ZTF, and YSE and were identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classifications were performed with SNID-SAGE (Toppa & Smartt, 2026, MNRAS, 549, 4).

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) The spectrum displays a featureless blue continuum. (2) We measure a Si II absorption velocity of -11,800 km/s.
