LIGO/Virgo S190814bv: No Optical Counterpart Candidates in Second-Epoch Lick/KAIT Observations
Abstract
The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, performed second-epoch follow-up observations of the gravitational-wave event S190814bv (GCN 25324) detected by LIGO/Virgo on Aug. 18 UT, in addition to the first-epoch observations conducted on Aug. 15 (Vasylyev et al., GCN 25353). 52 galaxies were observed based on their priority scores and elevation visibility, with each clear-filter exposure time being 60 s. Our typical limiting magnitude is 18.0. No viable counterparts were identified and the analysis is ongoing. A full list of galaxies observed by KAIT is given below.
