TITLE: GCN CIRCULAR NUMBER: 42571 SUBJECT: GRB 251103A: KAIT optical observations DATE: 25/11/04 08:07:10 GMT FROM: Weikang Zheng at UC Berkeley <weikang@berkeley.edu> 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 GRB 251103A (Hu et al., GCN 42534; Fermi GBM Team, GCN 42536; Wang et al., GCN 42552; Sonawane et al., GCN 42553; DeLaunay et al., GCN 42568) starting at 11:54 UT, 7.13 hours after the burst. A set of clear (roughly R) filter images were obtained. We clearly detected the afterglow (Schneider et al., GCN 42535; Turpin et al., GCN 42538; Gritsevich et al., GCN 42539; Izzo et al., GCN 42540; O'Neill et al., GCN 42543; Ghosh et al., GCN 42545; Schneider et al., GCN 42549; Breeveld et al., GCN 42554; Hellot et al., GCN 42559; Mo et al., GCN 42562) in our coadd image. We measure its brightness to be 19.4 +/- 0.2 mag (Vega) at mid time of 7.72 hours after the burst.
