TITLE: GCN CIRCULAR NUMBER: 44352 SUBJECT: EP-WXT trigger 01709260303: KAIT optical observations DATE: 26/04/20 06:33:01 GMT FROM: Weikang Zheng at UC Berkeley 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 01709260303 (Yin et al., GCN 44350) starting at 10:53 UT, about 3.5 hours after the trigger. A set of B,V,R,I and clear (roughly R) filter images were obtained and lasted for ~0.9 hours. We performed photometry on the suggested flare star Gaia DR3 4524306802880186496 and did not find obvious variability on its brightness at 0.1 mag level.
