We report the following classifications of optical transients from spectroscopic observations with KOSMOS on the KPNO Mayall 4-m telescope. Targets were supplied by the Pan-STARRS Survey for Transients (PSST) and Gaia. Observations were made on 2017 June 29 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Gaia17bki | AT2017elf | 00:57:06.74 | +08:58:21.18 | 0.031 | Ia | +24d | PS17dmj | AT2017eze | 20:42:48.64 | -11:36:47.13 | 0.055 | II | | PS17dmo | AT2017ezl | 21:30:58.02 | -07:05:05.81 | 0.028 | Ia | +15d |

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.
