TITLE: GCN CIRCULAR NUMBER: 25359 SUBJECT: LIGO/Virgo S190814bv: No Counterpart Candidates in Las Cumbres Observatory Galaxy Targeted Search DATE: 19/08/16 05:12:19 GMT FROM: Daichi Hiramatsu at Las Cumbres Observatory Daichi Hiramatsu (LCO/UCSB), D. Andrew Howell (LCO/UCSB), Curtis McCully (LCO), Iair Arcavi (Tel Aviv University), Jamison Burke (LCO/UCSB), David Sand (U. Arizona), and Stefano Valenti (UC Davis) on behalf of the Las Cumbres GW Follow-up Collaboration We report 300s g- and i-band images of the following galaxies (obtained from the GLADE 2.3 catalog) in the LIGO/Virgo S190814bv initial localization region (GCN 25324) with the Las Cumbres Observatory 1m telescopes (FoV of 26’.5 x 26’.5) at Sutherland, South Africa and CTIO, Chile. We find no obvious candidates after performing image subtraction using PS1 template images or from visual inspection (denoted by a *) where template images are not available.
