  "body": "WeiKang Zheng (UCB), Xuhui Han (NAOC), Pinpin Zhang (NAOC) and\n\nAlexei V. Filippenko (UCB) report on behalf of the KAIT GRB team:\n\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\n\nLick Observatory, automatically responded to the EP-WXT trigger\n\n(ID= 01709131085; Li et al., GCN 39068) starting at 05:09 UT,\n\nJan. 29th, ~20 minutes after the trigger. A set of images with 20s\n\nexposure time were obtained in B, V, R I and clear (roughly R)\n\nfilters. Observations lasted for about 3 hours. The high proper\n\nmotion star RX J0448.7+1003 reported by Li et al. (GCN 39068) was\n\ncovered by KAIT images. Photometry of the star show that its\n\nbrightness is at B~13.2 mag in our first B band image at 26.7\n\nminutes, increased to a peak of B~12.9 mag at 43.6 minutes, then\n\ndecreased afterward with B~13.6 mag at 187 minutes. We therefore\n\nconfirm that this EP-WXT trigger event is truly associated with\n\nthis stellar flare.\n",
