We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by K. Itagaki and PTSS. All observations were made on 2018 August 5 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name         | IAU Name  | RA (J2000)  | Dec (J2000)  | z     | Type | Phase | Notes
 
             | AT2018enb | 21:39:34.57 | +08:52:47.30 | 0.028 | Ia   | -2    | (1) 
PTSS-18hdi   | AT2018eog | 20:28:11.97 | -03:08:13.47 | 0.02  | II   | young | 
 

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) Similar to SN 1991bg. We measure a Si II 6355 velocity of -12,600 km/s.
