Vetere (ASDC) report on behalf of the\nSwift Team:\n\nAt 07:43:27 UT, Swift-BAT triggered and located GRB 060510 (trigger=209351). \nThe spacecraft slewed immediately.  The BAT on-board calculated location\nis RA,Dec 95.870d,-1.162d {06h 23m 29s,-1d 09' 43\"} (J2000), with an\nuncertainty of 3 arcmin (radius, 90% containment, stat+sys). \nThe BAT light curve shows a multi-peak structure with a total duration\nof ~30 sec.  The peak count rate was ~8000 counts/sec (15-350 keV),\nat ~1 seconds after the trigger. \n\nThe XRT began observing the field at 07:44:57 UT, 90 seconds after the\nBAT trigger. The on-board centroiding algorithm was confused by a cosmic ray \nclose to the X-ray afterglow and the position sent out in the automated GCN \nNotice was incorrect.  Using ground-processed data, we find a bright X-ray source\nlocated at RA(J2000) = 06h 23m 28.1s, Dec(J2000) = -01d 09' 44.9\", with an\nestimated uncertainty of 8 arcseconds (90% confidence radius). \nThis location is 11 arcseconds from the BAT on-board position, within\nthe BAT error circle. \n\nUVOT took a finding chart exposure of 100 seconds with the White\n(160-650 nm) filter starting 100 seconds after the BAT trigger. \nA fading source was found at RA,Dec = 06h 23m 28.0s -1d 09' 46\" (J2000)\nwith a mag of 18.2.  There is nothing in DSS.  No correction has been made\nfor the expected extinction corresponding to E(B-V) of 0.41. \n\nThis burst (trigger 209351) should not be confused with the second\nSwift-BAT trigger (209352) 38 minutes later.",
