    At 06:12:48 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230829 ***A*** (trigger=1188089).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 83.012, +66.125 which is 
   RA(J2000) = 05h 32m 03s
   Dec(J2000) = +66d 07' 30"
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 ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
