We report the following classifications from spectroscopic observations with the Kast spectrograph on the Shane telescope obtained on 2022 August 27 UT. The targets were 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
ZTF22abbirsn| AT2022rnn | 00:23:04.392 | +21:14:02.66 | 0.10 | Ia | -2 d | (1)
ZTF22abbkhja| AT2022rmp | 07:27:10.440 | +33:50:06.35 | 0.026 | Ia | -6 d | (2)

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 (from NED).
(1) We measure a Si II velocity of -10,000 km/s.
(2) We measure a Si II velocity of -13,000 km/s.
(3) The transient has a blue featureless continuum.
