We report the following classification from spectroscopic observations with the KAST spectrograph on the Shane telescope obtained on 2023 Jun 20 UT. The target was identified by ALeRCE in the ZTF data stream. The classification was performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF23aanptmz | AT2023ktw | 17:27:29.91 | +34:17:53.03 | 0.07 | Ia | -7d | (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 velocity of -14,000 km/s.
