Filippenko (UC Berkeley) report on\nbehalf of the KAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to Swift GRB 180113A (Ukwatta et al.,\nGCN 22325) starting at 03:57:49 UT, 70 minutes after the burst,\nand lasted for about 1.5 hours. Observations were performed with\na sequence in the clear (roughly R), V, and I filters, and the\nexposure time was 60 s per image. The field is relative crowded,\nafter a preliminay analysis using the subtraction method, we do\nnot detect any optical afterglow candidate within the Swift-BAT\nerror circle (Ukwatta et al., GCN 22325). The typical limiting\nmagnitude of our single clear image is about 19.5 mag calibrated\nto the APASS catalog.",
