Leicester), A. Moretti, G. Tagliaferri (OAB), L. \nAngelini, F. Marshall, and N. Gehrels (NASA/GSFC)  report on behalf of the \nSwift XRT team:\n\nThe Swift BAT instrument detected a GRB at 05:44:03 UT on 12th April 2005 \n(GCN Circ 3237). The observatory executed an automated slew to the BAT \nposition and the XRT began taking data at 05:45:42 UT.  The XRT was in \nAuto state but was not able to centroid on the afterglow due to low source \nbrightness. From downlinked data we find a uncataloged X-ray source \nlocated at:\n\nRA(J2000) = 12:04:25.3,\nDec(J2000) = -1:12:02.2.\n\nWe estimate an uncertainty of about 5 arcseconds radius (90% containment). \nThis position is 191 arcseconds from the BAT position reported in GCN \n3237.\n\n[GCN_OPS_NOTE (12apr05):  Per author's request, the \"050406\" in the Subject line\nwas changed to \"050412\".]",
