Mangano (INAF-IASF/Palermo), K. Hurley (UC-Berkeley), N. \nWhite, N. Gehrels (GSFC), B. Zhang (U. Nevada), report on behalf of the \nSwift XRT team:\n\nWe report a refined XRT position for GRB 050219a (Romano et al. 2005, GCN \n3036; Hullinger et al. 2005, GCN 3038), based on ground-processing of XRT \nPhoton-Counting mode data taken during the first orbit after the \nburst.  The refined position is:\n\nRA(J2000) = 11:05:38.8,\nDec(J2000) = -40:40:58.3.\n\nWe estimate an uncertainty of about 6.3 arcseconds.\n\nThe lightcurve of this burst is fading, with a steep power-law up to about \n200 s post-burst and a shallower power law at later times.\n\nSwift observations of this burst ended at 21:05:36.00 UT, when the Swift \nBAT triggered on GRB 050219b, which replaced GRB 050219a as the new GRB \ntarget in the on-board schedule.",
