We report the following classifications of optical transients from spectroscopic observations with GMOS on the Gemini-North telescope. Targets were supplied by DECam (ATEL #11344). All observations were made on 2018 May 10 UT. Classifications were performed with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

 
Name     | IAU Name  | RA (J2000)  | Dec (J2000)  |   z   | Type | Phase |  Notes
C17-0116 | AT2018bfp | 13:24:38.22 | -02:34:51.99 | 0.053 | Ib | | (1,3) C17-0119 | AT2018bfu | 13:15:28.99 | -13:19:32.36 | 0.045 | Ic | | (2)

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)-(2) Targets discovered in the Kepler K2 C17 field. (3) Classification somewhat uncertain, with some similarity to SNe IIb as well.
