Keto D. Zhang, Andrew Hoffman, Shaunak Modak, Thomas de Jaeger,
James Sunseri, Yukei Murakami, WeiKang Zheng, Benjamin Stahl,
and Alexei V. Filippenko (UC Berkeley) 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 gravitational-wavei
event S190728q (GCN 25187) 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 90 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 08:55:35, July
28th UT, about 2.17 hours after the trigger, and the last image at
12:10:36 UT. Our typical limiting mag is 19.0. No viable counterparts
were identified and the analysis is ongoing. A full list of galaxies
observed by KAIT is given below.
