We report the following the classification of AT2023vcn from spectroscopic observations with the Goodman spectrograph on the SOAR telescope using the AEON queue, made on 2023 Nov 15 UT. The target was supplied by YSE and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS23jlq | AT2023vcn | 03:35:17.472 | -27:45:03.81 | 0.086 | Ia-91T | +17d | (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 -13,500 km/s.
We thank the SOAR observatory staff for executing this observation.
