The faint source is to the WEST of the\nafterglow, not to the EAST as we reported. With this correction, our earlier\nreport and that of Mazaeva et al. (GCN 17111) are now in agreement.\n\nOur preliminary astrometry, based on SDSS DR9, for the afterglow is:\n\n  08:10:40.61 +22:13:01.7 J2000\n\nand for the fainter source:\n\n  08:10:40.41 +22:13:01.8 J2000\n\nThis astrometry may be refined as the afterglow fades and fainter source becomes\nmore clearly separated.\n\nWe thank Mazaeva et al. (GCN 17111) for bringing this error to our attention.",
