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 201203A (Dichiara et al.,\nGCN 28985) starting at 06:54:43 UT, 136 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 20 s\nper image. We do not detect any optical afterglow candidate within\nthe BAT position error circle (Dichiara et al., GCN 28985),\nneither in single image, nor in the co-add images.\nThe typical limiting magnitude of our single clear image is about\n18.0 mag calibrated to the USNOB1.0 catalog.\nOur observation is consistent with the non-detection reported by\nother groups (Jelinek et al, GCN 28986; Watson et al., GCN 28987). ���",
