At 13:00:27 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 221024 ***A*** (trigger=1131029). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 169.718, +33.041 which is
RA(J2000) = 11h 18m 52s
Dec(J2000) = +33d 02' 28"
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 ~1257 counts/sec (15-350 keV), at ~3 sec after the trigger.
