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 EP260623a (Wang et al.,\n\nGCN 45020, 45035; Svinkin et al., GCN 45046) at 5.85 hours after\n\nthe burst, and again at 1.34 days after the burst. A set of clear\n\n(roughly R) filter images were obtained. We clearly detected the\n\noptical afterglow (Li et al., GCN 45021; Izzo et al., GCN 45022;\n\nAngulo et al., GCN 45024; Brivio et al., GCN 45025; Jiang et al.,\n\nGCN 45026; Li et al., GCN 45027; Jelinek et al., GCN 45029; Lee\n\net al., GCN 45030; Saikia et al., GCN 45034; Bochenek & Perley,\n\nGCN 45040; Busmann et al., GCN 45042; Brivio et al., GCN 45045)\n\nin our coadd images. We measure its brightness decayed from\n\n18.8 +/- 0.1 mag (Vega) to 22.2 +/- 0.2 mag with a power-law\n\ndecay index of ~2.0.\n",
