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 240730A (Cenko et al.,
GCN 36976) starting at 10:24UT, ~2.53 hours after the burst. A
total of 50x60s images were obtained in the clear (roughly R)
filters. We do not detect any optical afterglow candidate within
the enhanced XRT position error circle (Evans et al., GCN 36977),
neither in single image, nor in the co-add images. The typical
limiting magnitude of our single clear image is about 19.5 mag
calibrated to the PS1 catalog.
