We report the following classifications of optical transients from spectroscopic observations with the Kast spectrograph on the Shane telescope. Targets were supplied by ATLAS and ZTF. All observations were made on 2018 Jul 08 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name         | IAU Name  | RA (J2000)  | Dec (J2000)  |   z   | Type | Phase  | Notes
 
ATLAS18rsi   | AT2018cwx | 23:01:12.28 | +04:15:36.87 | 0.05  |  Ic  |  +0 d  |  
ZTF18abdfaqi | AT2018cxm | 14:53:58.33 | +26:00:07.09 | 0.048 |  Ia  |  -5 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 -11,200 km/s.
