TITLE: GCN CIRCULAR NUMBER: 43110 SUBJECT: EP251214a: KAIT optical upper limit DATE: 25/12/15 07:28:01 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 EP251214a (Yin et al., GCN 43087; 43102) starting at 08:58, Dec 14 UT, about 6.52 hours after the burst. A set of 129x60s clear (roughly R) filter images were obtained. In our coadd image, we did not detect any new source within the EP-WXT error circle (Yin et al., GCN 43087) down to a limiting mag of 21.6 mag (Vega) at a mid-time of 8.88 hours after the burst. Our result is consistent with the upper limit reported by other groups (Basa et al., GCN 43092; Lipunov et al., GCN 43099).
