We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ZTF and YSE. All observations were made on 2019 Feb 2 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase | Notes
ZTF20aahzyml | AT2020atv | 10:05:05.98 | -12:07:35.73 | 0.08 | Ia | +3 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 an Si II 6355 velocity of -10,500 km/s. (2) We measure an Si II 6355 velocity of -11,700 km/s.
