    At 07:04:14 UT, the Swift Burst Alert Telescope (BAT) triggered and
    located GRB 220623 ***A*** (trigger=1111672).  Swift slewed immediately to the burst.
    The BAT on-board calculated location is 
    RA, Dec 145.462, +75.828 which is 
       RA(J2000) = 09h 41m 51s
       Dec(J2000) = +75d 49' 42"
    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 ~9007 counts/sec (15-350 keV), at ~0 sec after the trigger.
