    At 20:24:28 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231214 ***A*** (trigger=1202386).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 305.736, -72.436 which is 
   RA(J2000) = 20h 22m 57s
   Dec(J2000) = -72d 26' 09"
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 ~12989 counts/sec (15-350 keV), at ~13 sec after the trigger.
