Taggart (LJMU) report on \nbehalf of the GROWTH collaboration:\n\nWe obtained two 600-second exposures of ZTF19aarykkb (Kasliwal et al., \nGCN 24191) using the Spectrograph for the Rapid Acquisition of \nTransients (SPRAT) on the 2m Liverpool Telescope.\n\nThe reduced 1D spectrum shows a broad (full-width ~ 15000 km/s) emission \nline centered at 6700 Angstroms, which we associate with broad H-alpha \nfrom the transient.  Narrow H-alpha emission at z=0.025 (likely from the \nhost galaxy) is also detected.  We cannot confirm the presence of He II \n(tentatively reported by Pavana et al., GCN 24200) or any other \nsignificant features at this time.  These observations suggest that this \nsource is a young Type II supernova, and is unlikely to be associated \nwith the BNS merger S190425z (GCN 24168).\n\n\n\n\n\n\n\n\nDisclaimerNone",
