The optical afterglow was initially discovered by Thorstensen & Halpern (GCN 21897) on 2017 October 11 at 08:31 UT. Spectroscopic signatures of the associated SN were discovered by our group on 2017 November 1.

There is significant host contamination at the location of the afterglow, which was approximately removed using a spectrum of the adjacent region (the nucleus of the host) rescaled assuming no SN contribution at 3500 AA.
