WeiKang Zheng 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 GRB 250403A (Parsotan et
al., GCN 40292; Wang et al., GCN 40299) with a set of 120x60s
images in the clear (roughly R) filters, at a mid time of 13.9
hours after the trigger. We marginally detected the optical
afterglow (Parsotan et al., GCN 40292; Odeh et al., GCN 40295;
Garnichey et al., GCN 40301; Komesh et al., GCN 40307) in the
coadd image with a brightness of 21.7 +/- 0.3 mag (Vega).
