We report the following the classifications of AT2023aaga and AT2023aajf from spectroscopic observations with the Goodman spectrograph on the SOAR telescope using the AEON queue, made on 2023 Dec 18 UT. The targets were supplied by ATLAS and GOTO respectively, and identified using the target management platform YSE-PZ (Coulter et al., 2023, PASP, 135, 4501). The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ATLAS23xml | AT2023aaga | 03:09:36.199 | -54:03:00.15 | 0.0552 | Ia | -4d | (1)
GOTO23bwl | AT2023aajf | 04:22:41.531 | -51:29:15.28 | 0.0428 | Ia | -6d | (2)
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 -11,400 km/s.
(2) We measure a Si II 6355 absorption velocity of -12,300 km/s.
We thank the SOAR observatory staff for executing this observation.
