Yukei Murakami, Shaunak Modak, Keto Zhang, Thomas de Jaeger,
Benjamin Stahl, Andrew Hoffman, Nachiket Girish, WeiKang Zheng,
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 S190727h (GCN 25164) 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 166 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 08:02:37, July
27th UT, about 1.98 hours after the trigger, and the last image at
12:30:34 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.
