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
01709259586 (Wu et al., GCN 44213) starting at 05:46 UT, about 27
minutes after the trigger. A set of B,V,R,I and clear (roughly R)
filter images were obtained and lasted for ~1.5 hours. We performed
photometry on the suggested flare star UCAC4 498-055345 and did not
find obvious variability on its brightness at 0.1 mag level.
