Palmer (LANL) report on behalf of the Swift Team:\n\nAt 06:11:00 UT, the Swift Burst Alert Telescope (BAT) found a \nmarginal-significance peak (5.83 sigma) in a non-rate-triggered \n64 second image (trigger=592558).  Because the peak location was close\n(8.5 arcminutes) to a nearby galaxy, Swift slewed immediately to the \nlocation to make a confirmation observation with the narrow-field instruments. \nThe BAT on-board calculated location is \nRA, Dec 190.636, +11.579 which is \n   RA(J2000) = 12h 42m 33s\n   Dec(J2000) = +11d 34' 44\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows no obvious count\nrate variation. \n\nThe XRT began observing the field at 06:13:02.6 UT, 122.5 seconds after\nthe BAT trigger. No source was detected in 1.2 ks of promptly\ndownlinked data, which covered 97% of the BAT error circle. \n\nGiven the sub-threshold nature of the trigger, the lack of features in\nthe BAT light-curve and the fact that no X-ray source is detected, we\nbelieve this was just a noise event.",
