M. Parsons (GSFC), G. Sato (GSFC/JSPS/USRA) and\nM. Stamatikos (NASA/ORAU) report on behalf of the Swift Team:\n\nAt 18:15:44 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 060605 (trigger=213630).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA,Dec 322.144, -6.060 {21h 28m 35s, -06d 03' 36\"} (J2000)\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a FRED-like\nstructure with a duration of about 20 sec.  The peak count rate\nwas ~2000 counts/sec (15-350 keV), at ~0 sec after the trigger. \n\nThe XRT began taking data at 18:17:17 UT, 93 seconds after the BAT\ntrigger. The XRT on-board centroid algorithm did not find a source in\nthe image, however analysis of downlinked PC mode data finds a faint,\nuncatalogued point source at the following location: \nRA(J2000): 21h 28m 37.2s Dec(J2000): -06d 03m 35.3s, with an estimated \nerror of 4 arcsec radius (90% containment). This position is 39 arcsec \nfrom the center of the BAT error circle and is 4.5 arcsec from the\nUVOT candidate. \n\nUVOT took a finding chart exposure of 100 seconds with the White\n(160-650 nm) filter starting 98 seconds after the BAT trigger. There\nis a candidate afterglow in the rapidly available 2.7'x2.7' sub-image\nat (RA,DEC) (J2000) of (322.1555,-6.0587) or\n(21h28m37.32s,-06o03'31.3\")  with a 1-sigma error radius of about 0.5\narc sec. This position is 41.3 arc sec. from the centre of the BAT\nerror circle. The estimated magnitude is 17.4 with a 1-sigma error of\nabout 0.5 mag. No correction has been made for the expected extinction\ncorresponding to E(B-V) of  0.05.",
