At 13:18:25 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241115 ***A*** (trigger=1267921). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 86.765, -0.662 which is
RA(J2000) = 05h 47m 04s
Dec(J2000) = -00d 39' 44"
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 ~7661 counts/sec (15-350 keV), at ~1 sec after the trigger.
