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 EP241107a (Zhou et al.,

GCN 38112) on Nov 08 UT starting at ~0.67d after the trigger.

A set of 60x60s images were obtained in the clear (roughly R)

filters. We detect the optical afterglow (Odeh et al., GCN 38115;

SVOM/C-GFT team, GCN 38116; Lipunov et al., GCN 38117; Mohan et al.,

GCN 38118; Busmann et al., GCN 38120; Adami et al., GCN 38122;

Quirola-Vasquez et al., GCN 38126; Li et al., GCN 38127; Odeh

et al., GCN 38128; Kong et al., GCN 38131) in the coadd image and

measure its brightness to be 20.5 +/- 0.1 at a mid time of ~0.71d

after trigger.
