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).
