At 05:41:45 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 241101 ***A*** (trigger=1264304). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 204.333, +28.264 which is
RA(J2000) = 13h 37m 20s
Dec(J2000) = +28d 15' 49"
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 ~2351 counts/sec (15-350 keV), at ~1 sec after the trigger.
