TITLE: GCN CIRCULAR NUMBER: 39087 SUBJECT: The EP-WXT trigger 01709131085: KAIT confirmation of the stellar flare DATE: 25/01/29 20:04:00 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 (ID= 01709131085; Li et al., GCN 39068) starting at 05:09 UT, Jan. 29th, ~20 minutes after the trigger. A set of images with 20s exposure time were obtained in B, V, R I and clear (roughly R) filters. Observations lasted for about 3 hours. The high proper motion star RX J0448.7+1003 reported by Li et al. (GCN 39068) was covered by KAIT images. Photometry of the star show that its brightness is at B~13.2 mag in our first B band image at 26.7 minutes, increased to a peak of B~12.9 mag at 43.6 minutes, then decreased afterward with B~13.6 mag at 187 minutes. We therefore confirm that this EP-WXT trigger event is truly associated with this stellar flare.
