    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.
