We report the spectroscopic classification of ATLAS17iif obtained at the robotic Liverpool Telescope using the SPRAT spectrograph (4000 - 8000 A, 18 A resolution) on the night of 2017 July 07. The target was provided by the ATLAS survey, see Tonry et al. (2011, PASP, 123, 58) and Tonry et al. (ATel #8680). The spectrum is available from the IAU Transient Name Server.

 
Survey Name | IAU Name   | R.A. (J2000) | Dec. (J2000) | Disc. Date | Source | Disc. Mag. |  Spec. Date |  z    | Type | Phase | Notes 
ATLAS17iif  | SN 2017fek | 20:21:47.44  | -10:43:53.2  |  20170705  | ATLAS  |   17.2     |  20170708.1 | 0.033 |  SN  | -     | (1) 

(1) Blue featureless continuum with Halpha emission at z=0.033. At this redshift, the transient has an absolute magnitude of -18.7 mag (ATLAS o-band).
