We report the following classifications of optical transients from spectroscopic observations with the Goodman HTS on the SOAR 4m telescope. Targets were supplied by the All-Sky Automated Survey for Supernovae (ASAS-SN) and the Pan-STARRS Survey for Transients (PSST). Observations were made on 2017 May 1 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name         | IAU Name  | RA (J2000)  | Dec (J2000)  | z     | Type | Phase | Notes
ASASSN-17di | AT2017cam | 16:51:55.73 | -16:21:04.03 | 0 | CV | | PS17cqd | AT2017doq | 13:41:57.60 | -04:22:13.04 | 0.074 | Ia | +10d | PS17cpm | AT2017dmc | 10:15:13.50 | +00:57:22.57 | 0.072 | Ia | -2d | (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 Si II 6355 velocity of -10,200 km/s.
