Racusin (NASA/GSFC),\nA. Rowlinson (U Leicester) and M. Stamatikos (OSU/NASA/GSFC) report on\nbehalf of the Swift Team:\n\nAt 23:25:45 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 091127 (trigger=377179).  Swift did not immediately slew\nto the burst due to Earth limb constraint. \nThe BAT on-board calculated location is \nRA, Dec 36.571, -18.954 which is \n   RA(J2000) = 02h 26m 17s\n   Dec(J2000) = -18d 57' 12\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a multi-peaked\nstructure with a duration of about 10 sec.  The peak count rate\nwas ~30,000 counts/sec (15-350 keV), at ~1 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until \nT0+50 minutes. There will be no XRT or UVOT data until\nthis time. \n\nBurst Advocate for this burst is E. Troja (eleonora.troja 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.)",
