Siegel (PSU) report on behalf of the\nSwift Team:\n\nAt 11:15:25 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 130529A (trigger=556930).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 24.259, -64.138, which is \n   RA(J2000)  =  01h 37m 02s\n   Dec(J2000) = -64d 08' 17\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is typical for image triggers, the real-time\nTDRSS lightcurve does not show anything significant. \n\nThe XRT began observing the field at 11:17:18.0 UT, 112.6 seconds after\nthe BAT trigger. XRT found a bright, uncatalogued X-ray source located\nat RA, Dec 24.2798, -64.1493 which is equivalent to:\n   RA(J2000)  = +01h 37m 7.15s\n   Dec(J2000) = -64d 08' 57.5\"\nwith an uncertainty of 5.4 arcseconds (radius, 90% containment). This\nlocation is 52 arcseconds from the BAT onboard position, within the BAT\nerror circle. No event data are yet available to determine the column\ndensity using X-ray spectroscopy. \n\nThe initial flux in the 2.5 s image was 1.24e-09 erg cm^-2 s^-1 (0.2-10\nkeV). \n\nUVOT took a finding chart exposure of 150 seconds with the White filter\nstarting 122 seconds after the BAT trigger. No credible afterglow candidate has\nbeen found in the initial data products. The 2.7'x2.7' sub-image covers 100% of\nthe XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. \nData from the list of sources generated on-board are not available at this\ntime. No correction has been made for the expected extinction corresponding to\nE(B-V) of 0.02. \n\nBurst Advocate for this burst is V. D'Elia (delia AT asdc.asi.it). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
