  "body": "WeiKang Zheng and Alexei V. Filippenko (UC Berkeley) report on\nbehalf of the KAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to Swift GRB 150302A (Lien et al.,\nGCN 17526) starting at 05:44:50 UT, 134 s after the burst, under\nbright moon condition. First few images were useless until ~18\nminutes after the burst. Observations were performed with an\nautomatic sequence in the clear (roughly R), V, and I filters,\nand the exposure time was 20 s per image. We do not detect the\nafterglow candidate (Fynbo et al., GCN 17527) in our images,\nwith a limiting magnitude of R~17.8 (calibrated to USNO B1.0)\nat a mid-time of 18.9 minutes after the burst."
