We observed 17 galaxies within the 90% error volume of S190814bv (LVC GCN 25324) with the William Herschel Telescope, in co-ordination with several other telescopes on La Palma (Heintz et al. GCN 25325, Perley et al. GCN 25328, D���Avanzo et al. GCN 25331). Observations were obtained on 15 August 2019 between 03:28 and 04:49 UT. Galaxies were selected from the HOGWARTS code (https://gwtool.watchertelescope.ie/)). For each galaxy we obtained 3x60s r-band observations in good seeing. Comparison with archival Pan-STARRS imaging reveals no obvious counterparts in any cases to similar limiting magnitudes to the Pan-STARRS images, although we caution that fainter candidates close to their hosts could be omitted in such an inspection.
The locations of the galaxies observed are
