At 20:26:02 UT, the Swift Burst Alert Telescope (BAT) triggered and
located GRB 220618 ***A*** (trigger=1110865). Swift slewed immediately to the burst.
The BAT on-board calculated location is
RA, Dec 103.793, -1.531 which is
RA(J2000) = 06h 55m 10s
Dec(J2000) = -01d 31' 49"
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 ~726 counts/sec (15-350 keV), at ~2 sec after the trigger.
