At 01:36:50 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241025 ***A*** (trigger=1262165). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 333.330, +83.566 which is
RA(J2000) = 22h 13m 19s
Dec(J2000) = +83d 33' 59"
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 ~1812 counts/sec (15-350 keV), at ~2 sec after the trigger.
