Filippenko (UCB) report on behalf of the KAIT GRB team:\n\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory, automatically responded to the SVOM GRB\n\n251111A (Cheng et al., GCN 42637) starting at 05:12:13, 115 seconds\n\nafter the burst. Observations were performed in 3 x 3 tiling mode,\n\nand a set of clear (roughly R) filter images were obtained. The first\n\nimage covered the reported afterglow (López-Cámara et al., GCN 42638;\n\nWu et al., GCN 42639) position was at 05:14:50, 272 seconds after\n\nthe burst. We did not detect the afterglow in our clear images with\n\nthe following upper limit:\n\n\nmid t-t0(s)  exp(s) UL(mag)\n\n---------------------------\n\n 282            20  >18.5\n\n 561            20  >18.5\n\n 763            20  >18.5\n\n1042            20  >18.5\n\n1323            20  >18.5\n\n1690            40  >19.0\n\n2156            40  >19.0\n\n2613            40  >19.0\n\n3168            60  >19.5\n\n3813            60  >19.5\n\n4442            60  >19.5\n",
