Cenko (NASA/Goddard Space Flight Center) report on behalf of the\nKAIT GRB team:\n\nThe 0.76-m Katzman Automatic Imaging Telescope (KAIT), located at\nLick Observatory, responded to GRB 140518A (Swift trigger 599287;\nMelandri et al., GCN 16298) starting at 09:22:16 UT, 270 s after\nthe burst. Observations were performed with an automatic sequence\nin the clear (roughly R), V and I filters, and the exposure time\nwas 20 s per image. We detect a faint object within XRT error\ncircle at J2000 coordinates of:\n\nRA =  15:09:00.62\nDEC= +42:25:05.9\n\nwith uncertainty of about 1\". The object was only detected in the\nfirst clear band single image with mag R~18.3, no detection in\nfollowing single images. But it is marginally detected in the co-add\nof next 5 single images with mag R~19.0. We suggest this to be the\nafterglow of the GRB. All mags are calibrated to USNO B1.0 catalog. \n\n[GCN OPS NOTE(18may14): Per author's request, the Subject-line was\ncorrected from \"140418A\" to \"140518A\".]",
