    At 21:19:34 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231110 ***A*** (trigger=1195733).  Swift slewed immediately to the burst.
The BAT on-board calculated location is 
RA, Dec 356.296, +82.621 which is 
   RA(J2000) = 23h 45m 11s
   Dec(J2000) = +82d 37' 16"
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 ~2800 counts/sec (15-350 keV), at ~1 sec after the trigger.
