report on behalf of Lick/KAIT GW follow-up team:


The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at

Lick Observatory, observed the 90% region of the gravitationa-wavei

event S190814bv (GCN 25324) detected by LIGO/Virgo. More than one

thousand galaxies were selected from the Glade catalog V1.0

(Dalya et al., 2018, MNRAS, 479, 2374; http://aquarius.elte.hu/glade/)

according to their priority score. KAIT observed 161 of them based on

their priority scores and elevation visibility, with each clear-filter

exposure time being 60 s. The first image was taken at 08:48:31, Aug.

15th UT, about 11.63 hours after the trigger, and the last image at

12:36:25 UT. Our typical limiting mag is 18.0. No viable counterparts

were identified and the analysis is ongoing. A full list of galaxies

observed by KAIT is given below.
