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 S190828l (GCN 25503) 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 59 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 11:44:07, Aug.
29th UT, about 28.8 hours after the trigger, and the last image at
12:57:58 UT. Our typical limiting mag is 18.5. No viable counterparts
were identified and the analysis is ongoing. A full list of galaxies
observed by KAIT is given below.
