    At 05:52:15 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 230210 ***A*** (trigger=1153670).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 50.745, +7.153 which is 
       RA(J2000) = 03h 22m 59s
       Dec(J2000) = +07d 09' 11"
    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 ~814 counts/sec (15-350 keV), at ~-4 sec after the trigger.
