At 11:42:32 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 230723 ***A*** (trigger=1180410). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 250.379, -5.327 which is
RA(J2000) = 16h 41m 31s
Dec(J2000) = -05d 19' 37"
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 ~2223 counts/sec (15-350 keV), at ~1 sec after the trigger.
