Stamatikos (NASA/GSFC/ORAU) report on behalf of the Swift Team:\n\nAt 02:11:18 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 060522 (trigger=211117).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA,Dec 322.951, +2.876 {21h 31m 48s, +02d 52' 33\"} (J2000)\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  Since this was a 64-sec BAT image trigger, there is not\nenough information in the light curve at this time to describe the time \nprofile of the burst. The peak count rate was ~500 counts/sec (15-350 keV), \nat ~5 sec after the trigger. \n\nThe XRT began taking data at 02:13:40 UT, 142 seconds after the BAT\ntrigger. The XRT on-board centroid algorithm did not find a source in\nthe image, however analysis of initial downlinked data shows the\npresence of an uncatalogued point source at the following\ncoordinates: RA (J2000) = 21:31:44.9, Dec(J2000) = +02:53:08.5, with\nan error radius of 4.0 arcseconds (90% containment). This source is\n61 arcseconds from the BAT position. \n\nThe UVOT began a 100 s white exposure at 02:13:47. A point source is\ndetected in the XRT error circle with a white magnitude of 19.7. This\nsource is not present in the DSS. The coordinates of this source are\n21:31:44.8, +02:53:10 (J2000) with an uncertainty of +/- 0.6 arcsec\n(90% containment).",
