We report the following classification from spectroscopic observations with the KAST spectrograph on the Shane telescope obtained on 2023 Jan 31 UT. The target was supplied by ATLAS. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS23bnn | AT2023bbn | 15:45:35.75 | -17:00:53.55 | 0.039 | Ia | -2d | (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 velocity of -11,000 km/s.
