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 and 2m telescopes at Siding Spring, Australia. We find no obvious
candidates after performing image subtraction using SDSS images as
templates. Additional galaxies continue to be observed from our South
African and Chilean sites.
