    At 09:51:06 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 211129 ***A*** (trigger=1085430).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 274.557, +31.776 which is 
   RA(J2000) = 18h 18m 14s
   Dec(J2000) = +31d 46' 33"
with an uncertainty of 3 arcmin (radius, 90% containment, including 
systematic uncertainty).  The BAT light curve showed a [**double-peaked**]
structure with a duration of about TTT sec.  The peak count rate
was ~1818 counts/sec (15-350 keV), at ~0 sec after the trigger.
