    At 16:43:59 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231205 ***A*** (trigger=1200812).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 54.154, +27.146 which is 
   RA(J2000) = 03h 36m 37s
   Dec(J2000) = +27d 08' 47"
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 ~6444 counts/sec (15-350 keV), at ~-4 sec after the trigger.
