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, responded to EP240913a/GRB 240913C (Li et al.,\n\nGCN 37492; Yin et al., GCN Circ. 37493; Dasgupta et al., GCN 37505;\n\nPawar et al., GCN 37510) starting at 06:12 UT, Sep 14th, ~18.6\n\nhours after the trigger. A set of 30x60s images were obtained in\n\nthe clear (roughly R) filters. Preliminary analysis do not reveal\n\nany new optical counterpart candidate within the Swift-XRT error\n\ncircle of the X-ray counterpart candidate (Jiang et al., GCN 37497)\n\nneither in single image, nor in the co-add images, consistent with\n\nthe reports from Asquini et al. (GCN 37499) and Zhu et al. (GCN\n\n37500, 37501). The typical limiting magnitude of our single clear\n\nimage is about 19.5 mag, and about 20.5 mag in the co-add image.\n",
