GRB 190926A: KAIT Optical Upper Limit

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to Swift GRB 190926A (Melandri et al., GCN 25848) starting at ~59 minutes after the burst. Observations were performed in the clear (roughly R) filters, a total of 102 images were obtained and the exposure time was 60 s per image. We do not detect any optical afterglow candidate within the Enhanced XRT position error circle (Goad et al., GCN 25850), neither in single image, nor in the co-add images. The typical limiting magnitude of our single clear image is about 19.0 mag.
