TITLE: GCN CIRCULAR NUMBER: 38136 SUBJECT: EP241107a: KAIT optical observations DATE: 24/11/08 19:28:59 GMT FROM: Weikang Zheng at UC Berkeley 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 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.
