    At 05:48:03 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 241030 ***A*** (trigger=1263718).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 343.033, +80.439 which is 
       RA(J2000) = 22h 52m 08s
       Dec(J2000) = +80d 26' 20"
    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 ~11913 counts/sec (15-350 keV), at ~162 sec after the trigger.
