At 03:08:39 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231204 ***A*** (trigger=1200562). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 135.451, -40.147 which is
RA(J2000) = 09h 01m 48s
Dec(J2000) = -40d 08' 49"
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 ~820 counts/sec (15-350 keV), at ~3 sec after the trigger.
