  "body": "WeiKang Zheng (UCB), Xuhui Han (NAOC), Pinpin Zhang (NAOC) and\nAlexei V. Filippenko (UCB) report on behalf of the KAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to the fast X-ray transient EP240626a\nfrom the Einstein Probe (Wu et al. GCNC 36766) starting at 1.01 hours\nafter the trigger. A set of 30x60s images were obtained in the clear\n(roughly R) filters. Preliminary analysis do not reveal any optical\ncounterpart candidate within the EP-FXT position error circle\n(Wu et al. GCNC 36770), neither in single image, nor in the co-add\nimages. The typical limiting magnitude of our single clear image is\nabout 19.0 mag calibrated to the PS1 catalog.\n"
