[vsnet-grb-info 39652] EP-WXT trigger 01709200800 : KAIT optical observations
TITLE: GCN CIRCULAR NUMBER: 41587 SUBJECT: EP-WXT trigger 01709200800 : KAIT optical observations DATE: 25/08/29 06:20:25 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, observed the field of EP-WXT trigger 01709200800 (Ni et al., GCN 41561) starting at 11:39, Aug 27 UT, about 17 minutes after the trigger. A set of clear (roughly R) filter images were obtained and lasted for ~70 minutes. We performed the photometry on the suggested flare star LSPM J0220+3320 and saw some variation in the magnitude, which faded from 11.92 +/- 0.03 mag to 11.99 +/- 0.03 mag during our observation. The field was observed again on the following night at ~21.98 hours and lasted for ~2 hours. We saw similar variation in magnitude but in rising phase, suggesting it is a variable star.
