D. A. Perley (LJMU), Lana Salmon (UCD) on behalf of GRAWITA and other collaborations report:
We observed the position of the 10 galaxies listed below, with the 3.6m Italian
TNG telescope (Canary Islands, Spain), equipped with the DOLORES camera in
imaging mode. These targets were selected from the list of probable host galaxies
generated by the HOGWARTS code (https://gwtool.watchertelescope.ie/), consistent
with the 90% probability region of S190814bv (LIGO Scientific Collaboration and
Virgo Collaboration, GCN Circ. 25324). Similar lists were coordinated with collaborating
telescopes in La Palma as in Heintz et al. (GCN Circ. 25324) and Perley et al. (GCN Circ. 25328).
Each galaxy was observed for 2 minutes exposure in the SDSS r filter. Observations were
carried out on 2019 Aug 15 between 02:13 and 02:54 UT. Conditions were affected by the nearby
bright Moon and large airmass.
Visual inspection of the 10 fields does not reveal any new candidate compared with archival images
from the Pan-STARRS survey.
