24378 2026-07-25 04:56:34 Kishore C. Patra Kishore C. Patra, Ryan J. Foley (UCSC) UCSC SN II 0.049 1 UCSC We report the classification of this object with spectroscopic observations with the Kast spectrograph on the Shane telescope. 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. 2026TNSCR3054....1P
