Geier (GRANTECAN, IAC, ULL), on behalf of a \nlarger collaboration, report:\n\nFollowing the detection of AT2019wmy/ZTF19acyiflj (Andreoni et al. GCNC \n26416) within the error area of the GW event S191205ah (LVC, GCNC \n26350), we obtained an optical spectrum covering the range 3700-7400 A \nwith the 10.4m GTC telescope equipped with OSIRIS in La Palma (Spain) on \nDec 18.\n\nFor AT2019wmy/ZTF19acyiflj, a magnitude r'= 19.79 +/- 0.05 at 06:35 UT \nis derived. The GTC spectrum is consistent with a SN Ia at redshift z = \n0.081 +/- 0.003.\n\nTherefore we consider that AT2019wmy/ZTF19acyiflj is unrelated to the \nS191205ah GW alert.",
