We report the classifications of astrophysical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2026 September 21 UT. The targets were supplied by YSE and ZTF. Targets were 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) and SNID-SAGE (Toppa & Smartt, 2026, MNRAS, 549, 4).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
PS26hnc | AT2026abej | 21:01:31.82 | -00:08:55.93 | 0.029 | II | peak |
PS26hph | AT2026aboe | 21:16:39.65 | -00:46:11.89 | 0.0595 | Ia | peak | (1)
ZTF26abvdwrk | AT2026abyk | 20:08:19.856 | +50:40:27.98 | 0.024 | II | +7d |
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 -14,000 km/s.
