TITLE:   GCN CIRCULAR
NUMBER:  27064
SUBJECT: LIGO/Virgo S200213t: No counterpart candidates in KAIT observations
DATE:    20/02/14 06:49:44 GMT

Sergiy Vasylyev, James Sunseri, Nachiket Girish, Yukei Murakami,
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 S200223t (GCN 27042) 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 108 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 04:20:06, Feb.
13th UT, about 10 minutes after the trigger, and the last image at
12:02:48 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.
