We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ATLAS. All observations were made on 2017 April 20 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name       | IAU Name  | RA (J2000)  | Dec (J2000)  | z     | Type | Phase |  Notes
ATLAS17dzg | AT2017dae | 09:08:34.75 | +48:36:26.06 | 0.052 | Ia | -2 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 -10,200 km/s.
