We report the following the classification of AT2023zzk from spectroscopic observations with the LRIS spectrograph on the Keck I telescope, made on 2023 Dec 16 UT. The target was supplied by ZTF. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF23abtycgb | AT2023zzk | 03:38:52.780 | +40:59:19.02 | 0.020 | II | | (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 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.
