Cenko (NASA/Goddard Space Flight Center) report on behalf of the\nKAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to Swift GRB 131229A (Page et al.,\nGCN 15627) starting at 06:41:34 UT, 130 s after the burst.\nObservations were performed with an automatic sequence in the\nV, I, and clear(roughly R) filters, and the exposure time was\n20 s per image. Compared to the DSS image, we do not detect\nnew sources within XRT error circle. Typical limiting magnitude\nof our single clear image is about 19.4. We marginally detected\nthe source mentioned by Perley (GCN 15628) in our single clear\nimage with mag around 19.3, and confirming its non-changing\nbrightness.\n\n[GCN OPS NOTE(29dec13): Per author's request, the \"110 s after the burst\"\nwas changed to \"130\".]",
