    At 01:47:39 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231104 ***A*** (trigger=1194500).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 23.789, +83.791 which is 
   RA(J2000) = 01h 35m 09s
   Dec(J2000) = +83d 47' 27"
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 ~51123 counts/sec (15-350 keV), at ~0 sec after the trigger.
