Ziaeepour (UCL-MSSL) report on behalf of the Swift Team:\n\nAt 11:20:58 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 070517 (trigger=279494).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 277.579, -62.333 which is \n   RA(J2000)  =  18h 30m 19s\n   Dec(J2000) = -62d 19' 56\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve shows two peaks\nwith a duration of about 10 sec.  The peak count rate\nwas ~1000 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nThe XRT began taking data at 11:22:43 UT, 105 seconds after the BAT\ntrigger. The XRT on-board centroid algorithm did not find a source in\nthe image, but analysis of down-linked data yields a position:  \n  RA(J2000) = 18h 30m 29.4s   \n  Dec(J2000) = -62d 17' 50.8\" \nwith an uncertainty of 5.2 arcsec (radius, 90% containment). \nThis position is  2.4 arcmin from the BAT position. \n\nThe UVOT is unable to observe the field of GRB070517 due to the\npresence of a 4th magnitude star 8 arcmin from the burst's location. \nThe Galactic reddening in the direction of the burst is E(B-V) =\n0.15.",
