Stratta (ASDC) report on behalf\nof the Swift Team:\n\nAt 22:20:58 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 110119A (trigger=442978).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is RA, Dec 348.558, +5.985 which is \n   RA(J2000) = 23h 14m 14s\n   Dec(J2000) = +05d 59' 05\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a multi-peaked\nstructure with a duration of about 95 sec.  The peak count rate\nwas ~4500 counts/sec (15-350 keV), at ~35 sec after the trigger. \n\nThe XRT began observing the field at 22:21:56.0 UT, 57.6 seconds after\nthe BAT trigger. XRT found a bright, uncatalogued X-ray source located\nat RA, Dec 348.5881, +5.9874 which is equivalent to:\n   RA(J2000)  = 23h 14m 21.14s\n   Dec(J2000) = +05d 59' 14.6\"\nwith an uncertainty of 6.2 arcseconds (radius, 90% containment). This\nlocation is 108 arcseconds from the BAT onboard position, within the\nBAT error circle. No event data are yet available to determine the\ncolumn density using X-ray spectroscopy. \n\nUVOT took a finding chart exposure of 150 seconds with the White filter\nstarting 67 seconds after the BAT trigger. There is a candidate afterglow in\nthe rapidly available 2.7'x2.7' sub-image at\n  RA(J2000)  =\t23:14:20.61 = 348.58587\n  DEC(J2000) = +05:59:10.5  =\t5.98626\nwith a 90%-confidence error radius of about 0.61 arc sec. This position is 9.0\narc sec. from the center of the XRT error circle. The estimated magnitude is\n16.48 with a 1-sigma error of about  0.14. No correction has been made for the\nexpected extinction corresponding to E(B-V) of 0.12. \n\nBurst Advocate for this burst is E. Troja (eleonora.troja AT nasa.gov). \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.)",
