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.
