Ukwatta (GSFC/GWU) report on behalf of the Swift Team:\n\nAt 04:09:17 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 080325 (trigger=307604).  Swift slewed immediately to the burst. \nThe BAT on-board calculated location is \nRA, Dec 277.895, +36.511 which is \n   RA(J2000) = 18h 31m 35s\n   Dec(J2000) = +36d 30' 38\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  Because this is a 64-sec long image trigger, the\nTDRSS lightcurve does not show any significant signal (as is typical). \n\nThe XRT began observing the field at 04:11:49.2 UT, 151.9 seconds after\nthe BAT trigger. XRT found a bright, uncatalogued X-ray source located\nat RA, Dec 277.8920, +36.5221 which is equivalent to:\n   RA(J2000)  = 18h 31m 34.0s\n   Dec(J2000) = +36d 31' 19.5\"\nwith an uncertainty of 4.7 arcseconds (radius, 90% containment). This\nlocation is 40 arcseconds from the BAT onboard position, within the BAT\nerror circle. No event data are yet available to assess possible\nredshift constraints using X-ray spectroscopy and the nH-z relation\nfrom Grupe et al. (2007). \n\n\nUVOT took a finding chart exposure of 100 seconds with the White (160-650 nm)\nfilter starting 162 seconds after the BAT trigger. No afterglow candidate has\nbeen found in the initial data products. Image catalog data are not available\nat this time. The 8'x8' region for the list of sources generated on-board\ncovers 100% of the XRT error circle. The list of sources is typically complete\nto about 18 mag. No correction has been made for the expected extinction\ncorresponding to E(B-V) of 0.06. \n\n\n\n\nBurst Advocate for this burst is L. Vetere (vetere AT astro.psu.edu). \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.)",
