Palmer (LANL), B. Sbarufatti (INAF-OAB/PSU),\nE. Troja (NASA/GSFC/UMCP) and T. N. Ukwatta (LANL) report on behalf of\nthe Swift Team:\n\nAt 18:09:04 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 151004A (trigger=657564).  Swift did not slew due to the\nEarth-limb observing constraint.  The BAT on-board calculated location is \nRA, Dec 213.585, -64.947, which is \n   RA(J2000)  =  14h 14m 20s\n   Dec(J2000) = -64d 56' 49\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  As is typical for image triggers, the real-time\nlight curve does not show anything significant. \n\nDue to an observing constraint, Swift will not slew until T0+56.9\nminutes. There will be no XRT or UVOT data until this time. \n\nBurst Advocate for this burst is S. B. Cenko (brad.cenko AT nasa.gov). \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.)",
