We report the following the classification of AT2023ebt and AT2023edb from spectroscopic observations with the Goodman spectrograph on the SOAR telescope using the AEON queue, made on 2023 Mar 30 UT. The targets were supplied by the Young Supernova Experiment (YSE) and ALeRCE (selected from the ZTF data stream) respectively. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS23bbn | AT2023ebt | 15:07:10.162 | +09:38:08.28 | 0.043 | II | +30d | (1)
ZTF23aaeavsv | AT2023edb | 15:08:10.791 | +20:10:52.00 | 0.0441 | II | -3d | (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 H-alpha absorption velocity of -8,400 km/s.
(2) We measure a H-alpha absorption velocity of -13,300 km/s.
We thank the SOAR observatory staff for executing this observation.
