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, observed the field of EP250111a (Zhao et al.,\n\nGCN 38905) starting at 02:53:32 UT on 2025-01-11, ~1.55 hr after\n\nthe trigger. A set of clear (roughly R) band images were obtained.\n\nWe marginally detect the optical afterglow (Fu et al., GCN 38906;\n\nPankov et al., GCN 38913) in the 11x60s coadd image and measure\n\nits brightness to be 20.5 +/- 0.3 (Vega) at a mid time of ~2.70 hr\n\nafter the trigger.\n",
