Steele (LJMU) on behalf of a larger collaboration.\n\nWe report the following Liverpool Telescope follow-up observations of\nEM candidates reported to the collaboration in GCN 20518. Observations\nwere made with the SPRAT spectrograph, and supernova classifications\nwere obtained using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).\n\nPS17wt was observed on 2017-01-25 at 00:30 UT. Possibly some faint\nemission features - no clear evidence of transient distinct from host\ngalaxy emission.\n\nPS17yt was observed on 2017-01-25 at 01:50 UT. The spectrum is\nconsistent with a SN Type Ia at 9 days before peak, with z=0.069.\nGalaxy 2MASX J10035883+4902195 is at a 0.211 arcmin separation, and\nhas catalogue z=0.069742. The classification of this object as a Type\nIa is consistent with GCN 20521, which reports spectroscopic data\nobtained an hour prior to our observation.\n\nPS17tn was observed on 2017-01-25 at 02:37 UT. The spectrum is\nconsistent with a SN Type Ia at 2 days before peak, with z=0.040.\nGalaxy 2MASX J09431321+4118581 is at a 0.099 arcmin separation, and\nhas catalogue z=0.044759.\n\nPS17ua was observed on 2017-01-25 at 03:12 UT. The spectrum is\nconsistent with a SN Type Ia at 1 day before peak, with z=0.048.\nGalaxy 2MASX J09441179+3250341 is at a 0.102 arcmin separation, and\nhas catalogue z=0.045336.\n\nPS17of was observed on 2017-01-25 at 03:49 UT. The spectrum is\nconsistent with a SN Type II at 15 days after peak, with z=0.031.\n\n\n-- \n------------------------------------------------------\nC.M.Copperwheat\nAstrophysics Research Institute,\nLiverpool John Moores University\n------------------------------------------------------\nhttp://telescope.livjm.ac.uk\n------------------------------------------------------\nEmail: c.m.copperwheat@ljmu.ac.uk\nTel: +44 (0)151 231 2914\nFax: +44 (0)151 231 2921\n------------------------------------------------------",
