GCN Circular 36773

WeiKang Zheng (UCB), Xuhui Han (NAOC), Pinpin Zhang (NAOC) and
Alexei V. Filippenko (UCB) report on behalf of the KAIT GRB team:

The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at
Lick Observatory, responded to the fast X-ray transient EP240626a
from the Einstein Probe (Wu et al. GCNC 36766) starting at 1.01 hours
after the trigger. A set of 30x60s images were obtained in the clear
(roughly R) filters. Preliminary analysis do not reveal any optical
counterpart candidate within the EP-FXT position error circle
(Wu et al. GCNC 36770), neither in single image, nor in the co-add
images. The typical limiting magnitude of our single clear image is
about 19.0 mag calibrated to the PS1 catalog.
