    At 10:37:02 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 240311 ***A*** (trigger=1219543).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 244.853, -15.805 which is 
       RA(J2000) = 16h 19m 25s
       Dec(J2000) = -15d 48' 16"
    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 ~0 counts/sec (15-350 keV), at ~ sec after the trigger.
