    At 22:09:50 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 240313 ***A*** (trigger=1219990).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 85.955, +21.767 which is 
       RA(J2000) = 05h 43m 49s
       Dec(J2000) = +21d 46' 02"
    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.
