We report the following classifications of optical transients from spectroscopic observations with the Goodman spectrograph on the Southern Astrophysical Research (SOAR) telescope. Targets were supplied by ATLAS. All observations were made on 2017 Feb 24 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name | IAU Name | RA (J2000) | Dec (J2000) | z | Type | Phase   |  Notes
ATLAS16bcy | AT2017ays | 12:12:45.99 | +00:24:28.1 | 0.0205 | II | | (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 Halpha velocity of -7,500 km/s.
