Maguire (TCD), M. \nPerez Torres (IAC), report on behalf of the GW@WHT collaboration:\n\nWe obtained an optical spectrum of a number of transients discovered by \nZTF (Andreoni et al. GCN 26424) within the localization region of \nS191213g (LVC, GCN #26402)\n\nAll spectra were obtained on the night of 2019 Dec 14 using the ACAM \ninstrument mounted on the William Herschel Telescope located on the \nRoque de Los Muchachos Observatory, La Palma, Spain.\n\nAT2019wnn / ZTF19acymcna shows strong Halpha emission at z=0.2, which \ntogether with its location in the nucleus of its host galaxy is \nconsistent with an AGN outburst.\n\nAT2019wni / ZTF19acymcwv is a Type Ia supernova around +10d from maximum \nlight, at a redshift z=0.09.",
