    At 02:51:51 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 231204 ***A*** (trigger=1200559).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 135.714, -40.223 which is 
       RA(J2000) = 09h 02m 51s
       Dec(J2000) = -40d 13' 23"
    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 ~882 counts/sec (15-350 keV), at ~2 sec after the trigger.
