WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on

behalf of the KAIT GRB team:


The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at

Lick Observatory, responded to Swift GRB 240101A (Cenko et al.,

GCN 35448) starting at 15.57 hours after the burst. A total of

31x60s images were obtained in the clear (roughly R) filters.

We do not detect any optical afterglow candidate within the Enhanced

XRT position error circle (Beardmore et al., GCN 35452), neither in

single image, nor in the co-add images. The typical limiting magnitude

of our single clear image is about 18.5 mag calibrated to the PS1 catalog.
