Filippenko (UCB) report on behalf of\n\nthe KAIT GRB team:\n\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory, observed the field of GRB 250403A (Parsotan et\n\nal., GCN 40292; Wang et al., GCN 40299) with a set of 120x60s\n\nimages in the clear (roughly R) filters, at a mid time of 13.9\n\nhours after the trigger. We marginally detected the optical\n\nafterglow (Parsotan et al., GCN 40292; Odeh et al., GCN 40295;\n\nGarnichey et al., GCN 40301; Komesh et al., GCN 40307) in the\n\ncoadd image with a brightness of 21.7 +/- 0.3 mag (Vega).\n",
