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, observed the field of EP240930a (Hu et al.,
GCN 37834; Wang et al., GCN 37848) on Oct 22 and again on Oct
23 UT. A set of 70x60s images were obtained in each night in the
clear (roughly R) filters. We detect the optical afterglow
(Fu et al., GCN 37840; Fu et al., GCN 37842; Li et al., GCN 37844;
Ror et al., GCN 37845; Li et al., GCN 37846) in the coadd image and
measure the brightness to be 21.2 +/- 0.2 and 21.7 +/- 0.3 mag at
1.14 and 2.12 days after trigger respectively.
