GCN Circular 13607
J. Wren, W.T. Vestrand, P. Wozniak, and H. Davis, of Los Alamos National Laboratory report: A RAPTOR wide-field monitor located in Maui observed the location of Swift trigger 530267 (Marshall et al., GCN 13602) during the period that the Swift BAT was observing gamma-ray emission. The 10 s exposure began at 07:09:38.7 UTC -- 1 s after the Swift trigger and 1 s before the gamma-ray emission reached peak intensity. We detect no new object at the location of the refined Swift XRT location (Beardmore et al., GCN 13603) to a 3-sigma limiting magnitude of 10.3. Our unfiltered images are calibrated to the Tycho-2 V-band.
