TITLE: GCN CIRCULAR NUMBER: 20809 SUBJECT: LIGO/Virgo G275404: Liverpool Telescope classification of EM candidates DATE: 17/03/03 17:16:51 GMT FROM: Chris Copperwheat at LJMU ArI C.M.Copperwheat (LJMU), I.A.Steele (LJMU) and A.S.Piascik (LJMU) report on behalf of D.Bersier (LJMU), M.Bode (LJMU), C.Collins (LJMU), M.Darnley (LJMU), D.Galloway (Monash), A.Gomboc (Nova Gorica), S.Kobayashi (LJMU), A.

Ulaczyk (Warwick), K.Wiersema (Leicester) and the GROWTH (Global Relay of Observatories Watching Transients Happen) collaboration. --- We report the following Liverpool Telescope follow-up observations of EM candidates originally reported in GCN #20790. Observations were made with the SPRAT spectrograph, and supernova classifications were obtained using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024). iPTF17bqh was observed on 2017-03-02 at 23:58UT. The spectrum is generally featureless with some weak hints of Balmer lines in absorption, so we believe this source to be a dwarf nova in outburst. iPTF17bpt was observed on 2017-03-03 at 02:12UT. Based on a weather-affected spectrum we classify this transient as a type Ia SN at +18 days with z=0.595.
