Bradley Cenko\n(GSFC) report on behalf of the KAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to Swift GRB 120729A (Ukwatta et al.,\nGCN 13530) starting at 10:58:16 UT, 122 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. The bright optical afterglow (Ukwatta et al. GCN 13530,\nVirgili et al. GCN 13531, Oates et al. GCN 13539, Im et al. 13544,\nWren et al. 13545, Khamitov et al. GCN 13548, Gorosabel GCN 13550,\nD'Avanzo et al. GCN 13551, Smith et al. GCN 13554) was detected\nin all three filters. Useful observations lasted for about 2.4 hours.\nPreliminary analysis shows that the afterglow decays with a single\npower (with alpha = -0.87) beyond 1000 s after the burst.
