TITLE: GCN CIRCULAR NUMBER: 12684 SUBJECT: GRB 111209A: RAPTOR Limits Before and During the Gamma-ray Emitting Interval DATE: 11/12/15 17:32:20 GMT FROM: James Wren at LANL J. Wren, W. T. Vestrand, P. Wozniak, and H. Davis of Los Alamos National Laboratory report: The RAPTOR wide-field optical monitors were observing the location of GRB 111209A (Hoversten et al., GCN 12632) during the gamma-ray emitting interval as seen by the Swift BAT (Palmer et al., GCN 12640). Our system acquired 10 s exposures at 20 s intervals during the entire emission period. We have analyzed the the 77 images taken between T-150 and T+1400 and we do not detect the counterpart to a typical 3-sigma limiting magnitude of 10.3. Our unfiltered images were calibrated to the Tycho-2 V-band.
