At 05:48:03 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241030 ***A*** (trigger=1263718). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 343.033, +80.439 which is
RA(J2000) = 22h 52m 08s
Dec(J2000) = +80d 26' 20"
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 ~11913 counts/sec (15-350 keV), at ~162 sec after the trigger.
