At 07:48:13 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241113 ***A*** (trigger=1267501). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 16.576, -22.667 which is
RA(J2000) = 01h 06m 18s
Dec(J2000) = -22d 40' 00"
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 ~3811 counts/sec (15-350 keV), at ~183 sec after the trigger.
