Page (U Leicester), D. M. Palmer (LANL) and M. Perri (ASDC)\nreport on behalf of the Swift Team:\n\nAt 06:50:36 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 060719 (trigger=220020).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA,Dec 18.456, -48.375 {01h 13m 49s, -48d 22' 30\"} (J2000)\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows two peaks, the first\nstarting at T_zero for ~4 sec and the second starting at T+40 for ~15 sec. \nThe peak count rate is 3000 counts/sec (15-350 keV) at ~T+1 sec. \n\nThe XRT began observing the field at 06:51:53 UT, 77 seconds after the\nBAT trigger. XRT found a bright, variable, uncatalogued X-ray source\nlocated at RA(J2000) = 01h 13m 43.3s, Dec(J2000) = -48d 22' 53.5\", with an\nestimated uncertainty of 4.0 arcseconds (90% confidence radius). \nThis location is 64 arcseconds from the BAT on-board position, within\nthe BAT error circle. The initial flux in the 2.5s image was\n2.7e-09 erg/cm2/s (0.2-10 keV). \n\n\nUVOT took a finding chart exposure of 100 seconds with the White\n(160-650 nm) filter starting 90 seconds after the BAT trigger. No\nafterglow candidate has been found in the initial data products. The\n2.7'x2.7' sub-image covers 25% of the BAT error circle and 100% of\nthe ground-determined XRT error circle. The typical 3-sigma upper\nlimit has been about 18.5 mag. The 8'x8' region for the list of\nsources generated on-board covers 100% of the BAT error circle. The\nlist of sources is typically complete to about 18 mag. No correction\nhas been made for extinction.",
