Jonker (SRON/Radboud Univ) report on behalf of the GW@WHT collaboration:\n\nWe obtained optical spectroscopy of Gaia19dzi (GCN 25716), an optical transient within the LIGO/Virgo S190901ap  sky localisation (GCN 25606) with the ACAM instrument mounted on the William Herschel Telescope located at the Roque de Los Muchachos Observatory, La Palma, Spain. We cross-correlate the transient spectra with a library of supernova template spectra using the code SNID (Blondin and Tonry, 2007). \n\n\nGaia19dzi is classified as a SNIa, with a redshift of z=0.06. \n\n[GCN OPS NOTE(11sep19):  Per author's request, in the Subject-line and\nfirst sentence the \"S190910ap\" was changed to \"S190901ap\".]",
