Comparison of the spectrum of SN 2016jca obtained with the GTC on 01-January-2017 (t − t₀ = 13.3 days; shown in black), which was obtained near peak V-band light (+ 12.5 d, rest-frame). Plotted for comparison is a sample of GRB-SNe at similar post-explosion times: SN 1998bw (+ 13.3 days; blue), SN 2006aj (+ 13.0 days; green), SN 2013dx (+ 12.4 days; red) and the SN associated with GRB 140606B (+ 13.7 days; purple). All times and wavelengths are shown in the rest-frame. Visual inspection of the spectra reveals that the trough bluewards of the peak around 5000 ~ 5200 Å, which we attribute to blueshifted Fe ii λ5169, occurs at bluer wavelengths for SN 2016jca than all the comparison GRB-SNe, thus highlighting its high-velocity nature.
