At 14:43:11 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 240523 ***A*** (trigger=1231488). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 33.567, -22.020 which is
RA(J2000) = 02h 14m 16s
Dec(J2000) = -22d 01' 12"
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 ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
