    At 10:05:14 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 241010 ***A*** (trigger=1259578).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 153.365, +11.544 which is 
       RA(J2000) = 10h 13m 28s
       Dec(J2000) = +11d 32' 38"
    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 ~12442 counts/sec (15-350 keV), at ~0 sec after the trigger.
