We report the following the classification of AT2023dtz from spectroscopic observations with the Goodman spectrograph on the SOAR telescope using the AEON queue, made on 2023 Mar 24 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
ATLAS23eey | AT2023dtz | 12:41:24.898 | +13:43:51.71 | 0.020 | Ia | -4d | (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 absorption velocity of -12,100 km/s.
We thank the SOAR observatory staff for executing this observation.
