TITLE: GCN CIRCULAR NUMBER: 24488 SUBJECT: LIGO/Virgo S190510g: Las Cumbres Observatory Galaxy Targeted Counterpart Search DATE: 19/05/11 17:50:24 GMT FROM: Iair Arcavi at Tel Aviv University Iair Arcavi (Tel Aviv University), D. Andrew Howell (LCO/UCSB), Daichi Hiramatsu (LCO/UCSB), Jamison Burke (LCO/UCSB), Curtis McCully (LCO), Craig Pellegrino (LCO/UCSB), Paul Groot (Radboud University), 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; Dalya et al. 2018, MNRAS, 479, 2374) in the LIGO/Virgo S190510g localization region (Chu et al, GCN 24448) with the Las Cumbres Observatory 1m telescopes at the SAAO, South Africa and the CTIO, Chile. We find no significant counterpart candidates from visual inspection of the images.
