We report the classifications of astrophysical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2026 February 08 UT. The targets were supplied by ZTF and ALeRCE through the ZTF public data stream. 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).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF25acibrgc | AT2025ahdf | 09:49:31.32 | -15:33:12.86 | 0.06 | Ia | +40 d |
ZTF26aadsdgz | AT2026cdu | 11:11:55.76 | +57:04:36.74 | 0.14 | Ia | +6 d |
ZTF26aaffzys | AT2026cfz | 11:56:19.34 | +47:35:57.84 | 0.055 | Ib | -4 d | (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 He I 7065 absorption velocity of -7,900 km/s.
