Schady (MSSL-UCL), M. Stamatikos (NASA/ORAU),\nR. L. C. Starling (U Leicester), L. Vetere (PSU) and\nH. Ziaeepour (UCL-MSSL) report on behalf of the Swift Team:\n\nAt 20:35:32 UT, the Swift Burst Alert Telescope (BAT) triggered and\nlocated GRB 081121 (trigger=335105).  Due to an Earth limb constraint\nslew could not immediately slew to this burst. The BAT on-board \ncalculated location is \nRA, Dec 89.264, -60.626 which is \n   RA(J2000) = 05h 57m 03s\n   Dec(J2000) = -60d 37' 32\"\nwith an uncertainty of 3 arcmin (radius, 90% containment, including \nsystematic uncertainty).  The BAT light curve showed a single FRED\nstructure with a duration of about 15 sec, with overlying spikes. \nThere may be continued low-level emission out to 100 seconds. \nThe peak count rate was ~4000 counts/sec (15-350 keV), \nat ~1.5 sec after the trigger. \n\nDue to an observing constraint, Swift will not slew until \nT0+45.2 minutes. There will be no XRT or UVOT data until\nthis time. \n\nBurst Advocate for this burst is S. R. Oates (sro AT mssl.ucl.ac.uk). \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.)",
