    At 22:59:18 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 240314 ***A*** (trigger=1220094).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 81.671, +21.811 which is 
       RA(J2000) = 05h 26m 41s
       Dec(J2000) = +21d 48' 40"
    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 ~898 counts/sec (15-350 keV), at ~0 sec after the trigger.
