LIGO/Virgo S190828j: No counterpart candidates in KAIT observations

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, observed the 90% region of the gravitational-wavei event S190828j (GCN 25497) 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 84 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 07:10:51, Aug. 28th UT, about 37 minutes after the trigger, and the last image at 12:59:08 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.
