WeiKang Zheng, Keto Zhang, Sergiy Vasylyev and Alexei V. Filippenko
(UC Berkeley) report on behalf of the Lick/KAIT GW follow-up team:

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, observed the field of the gravitational-wave event
S190425z (GCN 24168) detected by LIGO/Virgo. More than one thousand
galaxies were selected from the Glade catalog (V1.0)
(http://aquarius.elte.hu/glade/)
according to their priority score. KAIT observed 101 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 09:06:22, Apr. 25 UT,
about 48 minutes after the trigger, and the last image at 12:43:52 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.
