We report the following classification from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2023 Jul 18 UT. The targets were supplied by the Young Supernova Experiment (YSE), GOTO, and ZTF. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
GOTO23le | AT2023lgj | 16:15:25.26 | +27:59:43.37 | 0.109 | Ia | +5d | (1)
ZTF23aansdlc | AT2023kqw | 14:36:43.33 | +12:05:24.27 | | SN | | (2)
PS23fel | AT2023min | 11:50:58.44 | +20:53:08.11 | | SN | | (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 velocity of -11,700 km/s.
(2) We detect a blue featureless continuum with no clear narrow features to constrain a redshift.
