WeiKang Zheng, Keto Zhang, Sergiy Vasylyev, Benjamin Stahl 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
S190421ar (GCN 24141) detected by LIGO/Virgo. More than one thousand
galaxies were selected from the Glade catalog
(http://aquarius.elte.hu/glade/)
according to their priority score. KAIT observed 159 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 03:52:11, Apr. 23 UT,
about 30.2 hrs after the trigger, and the last image at 08:22:03 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.
