Daichi Hiramatsu (LCO/UCSB), Craig Pellegrino (LCO/UCSB), Jamison Burke
(LCO/UCSB), D. Andrew Howell (LCO/UCSB), Iair Arcavi (Tel Aviv University),
Curtis McCully (LCO) on behalf of the Las Cumbres GW Follow-up Collaboration

We report 300s gri-band images of the following galaxies in the LIGO/Virgo
S190425z localization region (GCN 24168) with the Las Cumbres Observatory
1m telescopes at Sutherland, South Africa. We find no obvious candidates
after performing image subtraction using SDSS images as templates.
