  "body": "David Palmer reports on behalf of the Swift Team:\n\nIn two successive 64-second images, beginning at 06:56:51, BAT detected a source at a consistent\nlocation.  Although the individual images were below threshold, the combined detection\nis highly significant, in excess of 8 sigma.  A 320 s image that includes the data\nfrom both 64 s images indicates additional flux outside of the 128 s time interval.\n\nThe BAT on-board calculated location is RA,dec = 193.638,63.494 (J2000), which is\n  RA(J2000) =  12h 54m 33s\n  Dec(J2000) = +63d 29� 38�\n\nAs is usual for image triggers, there is no obvious variation in the BAT lightcurve.\n\nBecause the individual images were below threshold, Swift did not automatically\nslew to the location.  However, a ToO has been requested.\n\n-- \nDavid Palmer  palmer@lanl.gov   (505)665-6863 (voice)   (505)665-4414 (fax)",
