TITLE: GCN CIRCULAR NUMBER: 41298 SUBJECT: EP-WXT trigger 01709195487: KAIT confirmation of the stellar flare DATE: 25/08/08 21:07:33 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, automatically responded to the EP-WXT trigger 01709195487 (Liang et al., GCN 41173) starting at 07:40:52 UT, July 27th, 408 seconds after the trigger. A set of images in clear (roughly R) filters were obtained. Observations lasted for about 1.4 hours. The high proper motion star UPM J1905-2819 reported by Liang et al. (GCN 41173) was measured to be 10.86 +/- 0.02 mag at the beginning and decayed to be 11.07 +/- 0.02 mag at 1.4 hours later. The target was observed again in the following two nights with a measured magnitude of 11.16 +/- 0.02, confirming the EP X-ray trigger due to a stellar flare as also reported by Perez-Garcia et al. (GCN 41192).
