We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. The targets were supplied by ZTF. All observations were made on 2024 Aug 27 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF24aazqcuz | 2024rqt | 15:56:04.46 | +28:54:01.79 | 0.06101 | Ia | +4 | 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 measure a Si 6355 velocity of -10,200 km/s. The supernova is in a location between two host galaxies in an interacting system, and we cannot determine the exact host galaxy.
(2) We measure a Si 6355 velocity of -10,300 km/s.
