At 10:19:44 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230123 ***A*** (trigger=1150429). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 40.937, -65.676 which is
RA(J2000) = 02h 43m 45s
Dec(J2000) = -65d 40' 33"
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 ~1164 counts/sec (15-350 keV), at ~1 sec after the trigger.
