We report the classifications of AT2022yhl from spectroscopic observations with the LRIS spectrograph on the Keck I telescope obtained on 2022 Oct. 22 UT. The target was supplied by the Young Supernova Experiment. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS22koy | AT2022yhl | 02:27:30.971 | -01:06:35.15 | 0.0857 | Ia | -12d | (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 II 6355 velocity of -17,700 km/s.
