    At 05:05:59 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231129 ***A*** (trigger=1199764).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 317.536, +41.544 which is 
   RA(J2000) = 21h 10m 09s
   Dec(J2000) = +41d 32' 37"
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 ~3752 counts/sec (15-350 keV), at ~90 sec after the trigger.
