    At 18:50:39 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 240203 ***A*** (trigger=1212789).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 84.294, +22.160 which is 
       RA(J2000) = 05h 37m 11s
       Dec(J2000) = +22d 09' 35"
    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 ~945 counts/sec (15-350 keV), at ~3 sec after the trigger.
