We report the following classification from a spectroscopic observation with the Kast spectrograph on the Lick Shane telescope. The target was supplied by ATLAS. The observation was made on 2023 May 11 UT. Classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS23kbm | 2023hrn | 11:08:35.06 | +04:48:51.85 | 0.0231 | Ia | -7 | (1)
Notes:
The redshift was determined from the host galaxy emission lines in the supernova spectrum.
(1) We measure a Si II 6355 velocity of -14,500 km/s.
