report on behalf of the Lick/KAIT GW follow-up team:
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, performed second-epoch follow-up observations
of the gravitational-wave event S190814bv (GCN 25324) detected by
LIGO/Virgo on Aug. 18 UT, in addition to the first-epoch observations
conducted on Aug. 15 (Vasylyev et al., GCN 25353). 52 galaxies were
observed based on their priority scores and elevation visibility,
with each clear-filter exposure time being 60 s. Our typical
limiting magnitude is 18.0. No viable counterparts were identified and the
analysis is ongoing. A full list of galaxies observed by KAIT is given
below.
