We report the classifications of AT2023jwm from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2023 June 28 UT. The targets was supplied by ZTF. The classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF23aamumyw | AT2023jwm | 11:58:16.974 | +21:33:55.57 | 0.0678 | Ia | +15d | (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 -11,000 km/s.
