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 Swift Trigger 575905 (Cenko et al.,\nGCN 15384) starting at 06:42:00 UT, 148 s after the burst.\nObservations were performed with an automatic sequence in the\nV, I, and clear(roughly R) filters, and the exposure time was\n20 s per image. Comparing to the SDSS image, we do not detect\nnew sources within BAT error circle. Typical limiting magnitudes\nof our single clear image is about 18.7.",
