Sergiy Vasylyev, Yukei Murakami, Keto D. Zhang, WeiKang Zheng, 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 90% region of the gravitational-wave
event S200219ac (GCN 27130) 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 171 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 05:57:00, Feb.
20th UT, about 20.2 hours after the trigger, and the last image at
11:25:04 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.
