Siegel (PSU) report on behalf of the Swift\nTeam:\n\nAt 23:18:37 UT, the Swift Burst Alert Telescope (BAT) triggered (trigger=590503). \nSwift slewed immediately to the burst location. \nThe BAT light curve showed a strongly rising background \nlevel as Swift entered the SAA.  Combined with the low significance image trigger\n(5.81 sigma), we conclude that this trigger was caused by noise while entering \nthe SAA. \n\nThe XRT began observing the field at 23:20:52.7 UT, 135.7 seconds after\nthe BAT trigger. The only source detected is significantly outside the\nBAT error circle and has the morphology of a cosmic ray. This is\ntherefore unlikely to be a real detection.",
