La Parola (INAF-IASFPA), D. M. Palmer (LANL),\nP. Romano (INAF-IASFPA), B. Sbarufatti (INAF-IASFPA),\nM. Stamatikos (NASA/ORAU) and E. Troja (INAF-IASFPA) report on behalf\nof the Swift Team:\n\nAt 07:55:08 UT, the Swift Burst Alert Telescope (BAT) imaged and\nlocated Trigger 325461.  Swift slewed immediately to the location. \nThe BAT on-board calculated location is \nRA, Dec 130.138, -45.045 which is \n   RA(J2000) = 08h 40m 33s\n   Dec(J2000) = -45d 02' 40\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is typical for an image trigger,\nthere are no obvious variations in the TDRSS lightcurve. \nThis location is consistent with the Supergiant Fast X-ray Transient\n(SFXT) source IGR J08408-4503 (= LM Vel). \n\nThe XRT began observing the field at 07:57:32.6 UT, 143.7 seconds after\nthe BAT trigger. XRT found an X-ray source located\nat RA, Dec 130.1974, -45.0591 which is equivalent to:\n   RA(J2000)  = 08h 40m 47.37s\n   Dec(J2000) = -45d 03' 32.7\"\nwith an uncertainty of 4.9 arcseconds (radius, 90% containment). This\nlocation is 159 arcseconds from the BAT onboard position, within the\nBAT error circle, and is consistent with the SFXT IGR J08408-4503. \nNo event data are yet available to determine the\ncolumn density using X-ray spectroscopy. \n\nUVOT took a finding chart exposure of 400 seconds with the V filter starting\n881 seconds after the BAT trigger. Analysis will be reported later. \n\nBurst Advocate for this burst is V. Mangano (vanessa AT ifc.inaf.it). \nPlease contact the BA by email if you require additional information\nregarding Swift followup of this burst. In extremely urgent cases, after\ntrying the Burst Advocate, you can contact the Swift PI by phone (see\nSwift TOO web site for information: http://www.swift.psu.edu/too.html.)",
