At 03:03:19 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 231117 ***A*** (trigger=1197027). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 332.409, +13.514 which is
RA(J2000) = 22h 09m 38s
Dec(J2000) = +13d 30' 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 ~80585 counts/sec (15-350 keV), at ~0 sec after the trigger.
