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 150120A (D'Elia et al.,\nGCN 17310) starting at 02:59:24 UT, 98 s after the burst.\nObservations were performed with an automatic sequence in the\nclear (roughly R), V, and I filters, and the exposure time was\n20 s per image. We do not detect any new source in our\nimages within the enhanced XRT error circle (Evans et al.,\nGCN 17317). The typical limiting magnitude of our single clear\nimage is about 18.5 calibrated to USNO B1.0.",
