Abstract:
We report the spectroscopic classification of AT2023zzk as a SN II (see ATel #16384).
We report the classification of AT2023zzk as SN II from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2023 Dec 16 UT. The target was supplied by ZTF and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). We measure a H-alpha absorption velocity of -17,500 km/s. We thank the Keck Observatory staff, P. Gomez, and I. Caiazzo for their cooperation in the execution of this observation.
