TITLE: GCN CIRCULAR NUMBER: 14944 SUBJECT: GRB 130626A: KAIT Optical Observations DATE: 13/06/28 05:02:18 GMT FROM: Weikang Zheng at U.of Michigan WeiKang Zheng, Alexei V. Filippenko, Adam Morgan (UC Berkeley), and S. B. Cenko (NASA/Goddard Space Flight Center) report on behalf of the KAIT GRB team: The 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at Lick Observatory, responded to the short-duration GRB 130626A (De Pasquale et al., GCN 14931) starting at 10:52:40 UT, 97 s after the burst. Observations were performed with an automatic sequence in V, I, and clear filters (20 s exposure for each image). We detect the DSS source mentioned by Butler et al. (GCN 14943) in the corrected candidate XRT circle (Page et al., GCN 14937). We do not detect any new source in the XRT error circle. The estimated limiting magnitude in our first clear-band (close to R) image is about 18.7 (calibrated to USNO B1.0) at a midtime of 174 s after the burst.
