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.
