GCN Circular 15213
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 130912A (D'Elia et al., GCN 15212) starting at 08:48:04 UT, ~13 minutes after the burst. Observations were performed with an automatic sequence in V, I, and clear filters (20 s exposure for each image). Due to a technical issue, the first useful image begain ~35 minutes after the burst. 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 19.6 (calibrated to USNO B1.0) at a midtime of ~36 minutes after the burst.
