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 Trigger 797070 (Troja et al.,\nGCN 22254) starting at 04:21:09 UT, 340 s after the burst.\nObservations were performed with an automatic sequence in the\nclear (roughly R), V, and I filters, and the exposure time was 20 s\nper image. We do not detect any new source within the 3 arcmin\nSwift-BAT error circle (Troja et al., GCN 22254), either in single\nimage or the co-added images. Due to bad seeing condition, the typical\nlimiting magnitude of our single clear image is about 17.0 mag\ncalibrated to the APASS catalog, and the co-added image from 10 clear\nband images is about 17.5 mag.",
