No source is detected\ninside the BAT error circle, down to a 3-sigma upper limit of 2.7E-2 counts/s. \n\nThe Swift/UVOT began settled observations of the field 113 s after the BAT\ntrigger. No optical afterglow consistent with the BAT position\nis detected in the initial UVOT exposures.\n\nTherefore, we believe this trigger is due to a noise fluctuation.",
