TITLE: GCN CIRCULAR NUMBER: 43138 SUBJECT: EP251214b: KAIT optical upper limit DATE: 25/12/16 08:38:39 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 EP251214b (Jiang et al., GCN 43125) starting at 08:17, Dec 14 UT, about 0.95 hours after the trigger. A set of 29x60s and again 40x60s clear (roughly R) filter images were obtained. In our coadd images, we did not detect any new source within the EP-WXT error circle (Jiang et al., GCN 43125) down to limiting mag of 20.8 and 21.5 mag (Vega) at a mid-time of 1.23 and 3.12 hours after the trigger. Our result is consistent with the upper limit reported by other groups (Eyles-Ferris et al., GCN 43117; Lipunov et al., GCN 43127).
