Davis,\nof Los Alamos National Laboratory report:\n\nThe RAPTOR network of robotic optical telescopes made observations of Swift\ntrigger 536897 (Starling, et al., GCN 13913).  The burst location was within\nthe field of our wide-field monitor located in Maui, HI, which began a 10 s\nintegration of the location at 05:04:32.5 UT, 0.6 s after the Swift trigger\ntime and during the gamma-ray emitting interval including the time of peak\nemission detected by the BAT (Sakamoto, et al., GCN 13917).  We detect no\nnew object at the location of the refined Swift XRT location (Evans, et al.,\nGCN 13918).  Our 3-sigma limiting magnitude is 10.0 based on a comparison of\nour unfiltered image to the Tycho-2 V-band catalog.",
