D. A. Perley and C. M. Copperwheat (LJMU) report on behalf of the GROWTH
collaboration:
We obtained spectroscopy of several of the reported ZTF optical
transients (Andreoni et al., GCN 26424) inside the error region of
S191213g (LVC, GCN 26402) using the Spectrograph for the Rapid
Acquisition of Transients (SPRAT) on the 2m Liverpool
Telescope.��Observations were conducted on 2019-12-14 between 19:16 and
21:03 (UTC). Spectral classifications were performed with Superfit
(Howell et al. 2005).
The spectrum of ZTF19acykzsk (AT2019wqj) shows a broad emission feature
consistent with H-alpha at the host redshift of z=0.0205. ��The overall
spectrum is consistent with a Type II supernova close to maximum light.
